World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/african-clawed-frog): African Clawed Frog — wildlife guide.

## One-line answer
The African clawed frog is a fully aquatic frog from sub-Saharan Africa, named for the small dark claws on its hind feet. It has a flat body, no tongue or visible eardrum, and uses sensitive fingers and a lateral-line system to find food in murky water.

## Introduction
The African clawed frog is a fully aquatic frog from sub-Saharan Africa, named for the small dark claws on its hind feet. It has a flat body, no tongue or visible eardrum, and uses sensitive fingers and a lateral-line system to find food in murky water. Widely used in scientific research and kept as a pet, it can live 15 years or more.

## Takeaway
African clawed frogs spend almost their entire lives underwater, coming to the surface only to breathe.

## Takeaway
These frogs are scavenging carnivores that eat insects, worms, small fish, crustaceans, and bits of carrion.

## Takeaway
The African clawed frog is native to ponds, lakes, and slow-moving waters across sub-Saharan Africa.

## Behavior and adaptations
African clawed frogs spend almost their entire lives underwater, coming to the surface only to breathe. They lack a tongue and teeth, so they shove food into their mouths with their front fingers, and they use a sensitive lateral-line system along their bodies to detect movement in the water. The small black claws on their hind toes give the species its name and help tear apart food.

## Diet and feeding
These frogs are scavenging carnivores that eat insects, worms, small fish, crustaceans, and bits of carrion. They detect prey by smell, touch, and water vibrations rather than by sight. Their hearty appetite and tolerance of a wide range of conditions make them easy to keep.

## Habitat and range
The African clawed frog is native to ponds, lakes, and slow-moving waters across sub-Saharan Africa. It is extremely hardy and can survive in stagnant or polluted water and even travel short distances over land between pools. Released or escaped frogs have established invasive populations on several continents.

## Use in science and conservation
Xenopus laevis is one of the most important laboratory animals, long used in developmental biology, genetics, and, historically, human pregnancy testing. The species is listed as Least Concern and is abundant both in the wild and in captivity. Its main conservation impact is as an invasive species that can spread disease to native amphibians.

## WARN work
WARN does not run a dedicated african clawed frog programme — this guide is part of the World Animal Rescue Network's free educational library. The african clawed frog is currently widespread and not globally threatened, and this guide helps readers understand the pressures that can change that. Building public understanding of species like the african clawed frog supports the broader conservation awareness that underpins WARN's partner-led rescue work across its network.

World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/african-clawed-frog): African Clawed Frog — wildlife guide.

## Why is it called the African clawed frog?
It is named for the small, dark, claw-like structures on the toes of its hind feet, which it uses to tear apart food. The 'African' part refers to its native range in sub-Saharan Africa.

## What do African clawed frogs eat?
They are carnivores and scavengers that eat insects, worms, small fish, crustaceans, and carrion, pushing food into their mouths with their front fingers since they have no tongue.

## How long do African clawed frogs live?
African clawed frogs are long-lived and commonly reach 15 years or more in captivity with good care, which makes them a long-term commitment as pets.

## Why are African clawed frogs used in research?
They are hardy, breed readily, and produce large, easy-to-study eggs, making them a key model animal in developmental biology and genetics. They were also once used in human pregnancy tests.

## Are African clawed frogs invasive?
Yes, outside their native range. Released and escaped frogs have established wild populations on several continents, where they can outcompete native species and help spread amphibian diseases.

## Do African clawed frogs need land in their tank?
No. They are fully aquatic and spend their whole lives in water, surfacing only to breathe, so a pet setup needs deep water rather than a land area.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/fire-bellied-toad): Oriental Fire-bellied Toad — wildlife guide.

## One-line answer
The Oriental fire-bellied toad is a small, semi-aquatic amphibian from East Asia, recognized by its green and black back and its vivid red-and-black underside. When threatened, it arches its body to flash the bright belly, warning predators that its skin is toxic.

## Introduction
The Oriental fire-bellied toad is a small, semi-aquatic amphibian from East Asia, recognized by its green and black back and its vivid red-and-black underside. When threatened, it arches its body to flash the bright belly, warning predators that its skin is toxic. These hardy, popular pet toads commonly live 12 to 15 years, sometimes longer.

## Takeaway
Fire-bellied toads are active by day and spend much of their time in or near water.

## Takeaway
These toads are carnivores that eat insects, worms, snails, and other small invertebrates.

## Takeaway
The Oriental fire-bellied toad lives in Korea, northeastern China, and parts of southeastern Russia, in slow streams, ponds, marshes, and rice paddies.

## Behavior and the warning display
Fire-bellied toads are active by day and spend much of their time in or near water. Their most famous behavior is the unken reflex: when alarmed, the toad arches its back and lifts its limbs to display the bright red-and-black belly, a warning of the toxins in its skin. These mild toxins can irritate the eyes and mouth of a predator.

## Diet and feeding
These toads are carnivores that eat insects, worms, snails, and other small invertebrates. They hunt by sight and lunge at moving prey, often near the water's edge. In captivity they readily take crickets, mealworms, and earthworms.

## Habitat and range
The Oriental fire-bellied toad lives in Korea, northeastern China, and parts of southeastern Russia, in slow streams, ponds, marshes, and rice paddies. It favors cool, shallow water with plenty of vegetation and basking spots. It is semi-aquatic, splitting its time between water and damp land.

## Conservation and as a pet
The species is listed as Least Concern and remains common across its range. It is one of the most widely kept pet amphibians because it is hardy, active, and long-lived. Owners should handle it sparingly, as its skin secretions can irritate human skin and eyes.

## WARN work
WARN does not run a dedicated oriental fire-bellied toad programme — this guide is part of the World Animal Rescue Network's free educational library. The oriental fire-bellied toad is currently widespread and not globally threatened, and this guide helps readers understand the pressures that can change that.

World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/fire-bellied-toad): Oriental Fire-bellied Toad — wildlife guide.

## Why do fire-bellied toads have red bellies?
The bright red-and-black belly is a warning signal. When threatened, the toad arches its body to flash its underside, telling predators that its skin contains toxins and that it would be an unpleasant meal.

## Are fire-bellied toads poisonous?
Yes, mildly. Their skin secretes toxins that can irritate the eyes and mouth of predators and the skin of people who handle them, so it is best to wash your hands after any contact.

## What do fire-bellied toads eat?
They are carnivores that eat insects, worms, snails, and other small invertebrates, readily taking crickets, mealworms, and earthworms in captivity.

## How long do fire-bellied toads live?
Oriental fire-bellied toads are long-lived for their size, commonly reaching 12 to 15 years and sometimes more with good care.

## Are fire-bellied toads good pets?
Yes. They are popular, hardy, and active pets that do well in a semi-aquatic setup with water and land, though they should be handled sparingly because of their skin secretions.

## Where do fire-bellied toads live?
They live in Korea, northeastern China, and parts of southeastern Russia, in slow streams, ponds, marshes, and rice paddies with shallow water and vegetation.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/caecilian): Caecilian — wildlife guide.

## One-line answer
Caecilians are a group of limbless, worm-like amphibians that live mostly hidden in damp soil and leaf litter across the tropics of Africa, Asia, and the Americas. They range from a few centimeters to over 1.5 m (5 ft) long, have tiny or skin-covered eyes, and rely on a pair of sensory tentacles to find prey underground.

## Introduction
Caecilians are a group of limbless, worm-like amphibians that live mostly hidden in damp soil and leaf litter across the tropics of Africa, Asia, and the Americas. They range from a few centimeters to over 1.5 m (5 ft) long, have tiny or skin-covered eyes, and rely on a pair of sensory tentacles to find prey underground. Long-lived for amphibians, some caecilians survive well over a decade.

## Takeaway
Caecilians are secretive amphibians that spend most of their lives burrowing through moist soil and leaf litter, and a few species are fully aquatic.

## Takeaway
Caecilians are carnivores that eat earthworms, termites, insect larvae, and other small invertebrates found underground.

## Takeaway
As a group, caecilians live across the wet tropics of Africa, Asia, and Central and South America, with none in most temperate regions.

## Behavior and senses
Caecilians are secretive amphibians that spend most of their lives burrowing through moist soil and leaf litter, and a few species are fully aquatic. With no limbs, they move like worms or snakes, pushing through the ground with a strong, muscular body. Their eyes are tiny and often covered by skin or bone, so they navigate using a unique pair of retractable tentacles between the eyes and nostrils that detect chemicals and prey.

## Diet and feeding
Caecilians are carnivores that eat earthworms, termites, insect larvae, and other small invertebrates found underground. They seize prey with strong jaws lined with backward-curving teeth and may spin to subdue it. Their underground lifestyle keeps them close to a steady supply of soil-dwelling animals.

## Habitat and range
As a group, caecilians live across the wet tropics of Africa, Asia, and Central and South America, with none in most temperate regions. They favor warm, damp environments such as rainforest soil, riverbanks, and leaf litter. Because they live hidden underground or in water, they are rarely seen and remain among the least-known amphibians.

## Reproduction and conservation
Caecilians have remarkable reproduction: some lay eggs while others give birth to live young, and in several species the young feed on a special layer of their mother's skin. As a diverse group their conservation status varies by species, with many too poorly known to assess, while some face threats from habitat loss. Their secretive habits mean scientists are still discovering new kinds.

## WARN work
WARN does not run a dedicated caecilian programme — this guide is part of the World Animal Rescue Network's free educational library. The caecilian is currently widespread and not globally threatened, and this guide helps readers understand the pressures that can change that. Building public understanding of species like the caecilian supports the broader conservation awareness that underpins WARN's partner-led rescue work across its network.

World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/caecilian): Caecilian — wildlife guide.

## What is a caecilian?
A caecilian is a limbless, worm-like amphibian that lives mostly underground in damp tropical soil. Despite looking like worms or snakes, caecilians are amphibians, related to frogs and salamanders.

## Are caecilians worms or snakes?
Neither. Caecilians are amphibians that have evolved a long, limbless body for burrowing, which makes them resemble large earthworms or snakes, but they are not closely related to either.

## What do caecilians eat?
Caecilians are carnivores that eat earthworms, termites, insect larvae, and other small invertebrates they encounter in the soil, gripping prey with strong, toothed jaws.

## Can caecilians see?
Only poorly. Their eyes are tiny and often covered by skin or bone, so instead of relying on sight they use a special pair of tentacles to sense chemicals and locate prey in the dark.

## Where do caecilians live?
They live in the wet tropics of Africa, Asia, and Central and South America, in damp soil, leaf litter, and riverbanks, where they stay hidden most of the time.

## Do caecilians care for their young?
Yes, in some species. The young of certain caecilians feed on a nutrient-rich outer layer of their mother's skin, an unusual form of parental care among amphibians.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/golden-eagle): Golden Eagle — wildlife guide.

## One-line answer
The golden eagle (Aquila chrysaetos) is one of the largest and fastest birds of prey, found across the mountains, open hills, and tundra of the Northern Hemisphere. It weighs around 4.5 kg with a wingspan of 1.8 to 2.3 m, and in a hunting dive it can exceed 240 km/h (150 mph).

## Introduction
The golden eagle (Aquila chrysaetos) is one of the largest and fastest birds of prey, found across the mountains, open hills, and tundra of the Northern Hemisphere. It weighs around 4.5 kg with a wingspan of 1.8 to 2.3 m, and in a hunting dive it can exceed 240 km/h (150 mph). This powerful aerial hunter takes hares, marmots, and birds, lives 20 to 30 years, and is listed as Least Concern.

## Takeaway
The golden eagle is a large, dark-brown raptor named for the golden feathers that gleam on the nape and crown.

## Takeaway
The golden eagle is a superb flier that hunts on the wing, soaring on rising air and then folding its wings into a steep, high-speed stoop.

## Takeaway
Golden eagles range widely across the Northern Hemisphere, breeding in North America, Europe, North Africa, and much of Asia.

## Appearance and identification
The golden eagle is a large, dark-brown raptor named for the golden feathers that gleam on the nape and crown. Adults weigh around 4.5 kg and span 1.8 to 2.3 m (6 to 7.5 ft) from wingtip to wingtip, with females noticeably larger than males. In flight it holds its long, broad wings in a shallow V and soars with only occasional wingbeats. Young birds show white patches at the base of the tail and in the wings that fade as they mature.

## Hunting and flight
The golden eagle is a superb flier that hunts on the wing, soaring on rising air and then folding its wings into a steep, high-speed stoop. In such a dive it can exceed 240 km/h (150 mph), striking prey with long, powerful talons. It is a carnivore that takes hares, rabbits, marmots, ground squirrels, and birds up to the size of a goose, and readily feeds on carrion in winter. Pairs sometimes hunt cooperatively, one flushing prey while the other makes the kill.

## Habitat and range
Golden eagles range widely across the Northern Hemisphere, breeding in North America, Europe, North Africa, and much of Asia. They favour open, rugged country such as mountains, moorland, hills, and tundra where they can spot prey from the air. Large home ranges and cliff or tree nest sites are essential to a breeding pair. In Britain the species survives mainly in the Scottish Highlands and islands.

## Nesting and reproduction
Golden eagles pair for life and build huge stick nests, called eyries, on cliff ledges or in tall trees, reusing and enlarging them over many years. The female usually lays one to three eggs, and the pair defends a large territory throughout the breeding season. Where more than one chick hatches, the older and stronger often outcompetes its sibling. Young birds fledge after around ten weeks but depend on their parents for some time before dispersing.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/golden-eagle): Golden Eagle — wildlife guide.

## Lifespan and behaviour
Golden eagles are long-lived, typically reaching 20 to 30 years in the wild. They are territorial and largely solitary outside the breeding pair, patrolling extensive ranges in search of food. Their eyesight is exceptionally sharp, letting them detect prey from great distances as they soar. Revered in many cultures, the golden eagle has long been a symbol of power and remains an emblem of wild, mountainous country.

## Conservation status
The golden eagle is listed as Least Concern by the IUCN and remains widespread across its huge global range. Even so, it faces regional threats from illegal persecution, poisoning, collisions with power lines and wind turbines, and disturbance at nest sites. In some countries, including Britain, populations are recovering thanks to legal protection and reduced persecution. Safeguarding large tracts of open upland habitat is important for its long-term future.

World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/golden-eagle): Golden Eagle — wildlife guide.

## How fast can a golden eagle fly?
In a hunting dive, or stoop, a golden eagle can exceed 240 km/h (150 mph). In level flight it is much slower, cruising and soaring on rising air to conserve energy.

## What do golden eagles eat?
They are carnivores that hunt hares, rabbits, marmots, ground squirrels, and birds up to the size of a goose. In winter they also feed readily on carrion when live prey is scarce.

## How big is a golden eagle?
Adults weigh around 4.5 kg and have a wingspan of 1.8 to 2.3 m (6 to 7.5 ft). Females are noticeably larger than males, as in most birds of prey.

## Where do golden eagles live?
They range across the Northern Hemisphere in North America, Europe, North Africa, and Asia, favouring mountains, open hills, and tundra. In Britain they survive mainly in the Scottish Highlands and islands.

## How long do golden eagles live?
In the wild golden eagles typically live 20 to 30 years. They pair for life and can raise young over many breeding seasons in the same territory.

## Are golden eagles endangered?
No. The golden eagle is listed as Least Concern by the IUCN and is widespread globally. Regional threats include illegal persecution, poisoning, and collisions with power lines and wind turbines.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/great-horned-owl): Great Horned Owl — wildlife guide.

## One-line answer
The great horned owl is a large, powerful owl found throughout the Americas, named for the tufts of feathers on its head that look like horns or ears. A fierce nocturnal predator with crushing talons, it hunts a wide range of prey, even skunks and other raptors.

## Introduction
The great horned owl is a large, powerful owl found throughout the Americas, named for the tufts of feathers on its head that look like horns or ears. A fierce nocturnal predator with crushing talons, it hunts a wide range of prey, even skunks and other raptors. Known for its deep hooting call, it usually lives 10 to 15 years in the wild.

## Takeaway
The great horned owl is one of the most powerful birds of prey in the Americas, with a grip strong enough to crush the spine of its prey.

## Takeaway
Few predators have such a varied diet.

## Takeaway
The "horns" are not ears but tufts of feathers that may help with camouflage and communication; the owl's actual ears are hidden at the sides of its head and are set unevenly to pinpoint sound.

## A formidable night hunter
The great horned owl is one of the most powerful birds of prey in the Americas, with a grip strong enough to crush the spine of its prey. It hunts at night using exceptional hearing and large, light-gathering eyes, gliding silently on soft-edged feathers that muffle the sound of its wings so prey never hears it coming.

## Diet and fearless appetite
Few predators have such a varied diet. Great horned owls take rabbits, rodents, and other mammals, as well as birds up to the size of geese and other owls and hawks. They are one of the only animals that regularly hunt skunks, apparently untroubled by the spray, and they will also eat reptiles, amphibians, and large insects.

## The tufts and the hoot
The "horns" are not ears but tufts of feathers that may help with camouflage and communication; the owl's actual ears are hidden at the sides of its head and are set unevenly to pinpoint sound. Its deep, soft "hoo-hoo-hoo" is a classic sound of the night and is often the call people picture when they imagine an owl.

## Habitat and range
Great horned owls are found from the Arctic edge of North America down through Central and South America, living in almost every habitat, including forests, deserts, swamps, farmland, and city parks. This adaptability and their broad diet make them one of the most widespread and successful owls in the New World.

## WARN work
WARN does not run a dedicated great horned owl programme — this guide is part of the World Animal Rescue Network's free educational library. The great horned owl is currently widespread and not globally threatened, and this guide helps readers understand the pressures that can change that. Building public understanding of species like the great horned owl supports the broader conservation awareness that underpins WARN's partner-led rescue work across its network.

World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/great-horned-owl): Great Horned Owl — wildlife guide.

## What do great horned owls eat?
They are carnivores with a remarkably broad diet, including rabbits, rodents, birds as large as geese, other owls and hawks, reptiles, and even skunks, which few other predators will tackle.

## Do great horned owls really have horns?
No. The "horns" are tufts of feathers on the head, not horns or ears. They may aid camouflage and communication, while the owl's real ears are hidden on the sides of its head.

## How strong is a great horned owl's grip?
Their talons can clamp with great force, strong enough to subdue prey larger than themselves. This crushing grip is one reason they can take animals as formidable as skunks and other raptors.

## How long do great horned owls live?
In the wild great horned owls usually live 10 to 15 years, while protected birds in captivity have lived 20 to 30 years or more.

## Why are great horned owls associated with the classic owl hoot?
Their deep, resonant "hoo-hoo-hoo" carries far through the night and is the sound many people picture when they think of an owl, making them one of the most recognizable owls by voice.

## Are great horned owls dangerous to people?
They rarely bother people but can be very defensive near their nests and have been known to strike intruders who come too close. Away from the nest they avoid humans and pose little risk.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/peregrine-falcon): Peregrine Falcon — wildlife guide.

## One-line answer
The peregrine falcon (Falco peregrinus) is a crow-sized bird of prey found on every continent except Antarctica, making it one of the most widespread birds in the world. It hunts other birds in mid-air and is the fastest animal on the planet, reaching over 380 km/h (240 mph) in a hunting dive.

## Introduction
The peregrine falcon (Falco peregrinus) is a crow-sized bird of prey found on every continent except Antarctica, making it one of the most widespread birds in the world. It hunts other birds in mid-air and is the fastest animal on the planet, reaching over 380 km/h (240 mph) in a hunting dive. Adults weigh around 0.9 kg and live up to 15 years in the wild. The species is listed as Least Concern by the IUCN.

## Takeaway
No creature moves faster than a peregrine falcon in its hunting dive, known as a stoop.

## Takeaway
Peregrines are specialist bird-hunters, taking pigeons, ducks, starlings, and shorebirds almost exclusively on the wing.

## Takeaway
The peregrine is one of the most widely distributed birds on Earth, breeding on every continent except Antarctica and on many oceanic islands.

## The fastest animal alive
No creature moves faster than a peregrine falcon in its hunting dive, known as a stoop. Folding its wings tight against its body, the bird drops from height and can exceed 380 km/h (240 mph), far outpacing any cheetah or racing car. Special baffles in its nostrils are thought to keep the rushing air from damaging its lungs, and a third eyelid clears debris from its eyes mid-plunge. In level flapping flight it is far slower, so the record speed belongs entirely to the vertical dive.

## Hunting and diet
Peregrines are specialist bird-hunters, taking pigeons, ducks, starlings, and shorebirds almost exclusively on the wing. The falcon climbs high above its quarry, then stoops at tremendous speed and strikes with clenched talons, the impact alone often killing or stunning the target. It then follows the falling bird down to finish the kill or catches it in the air. This aerial ambush is why open country, coastlines, and cliff edges suit the peregrine so well.

## Where peregrines live
The peregrine is one of the most widely distributed birds on Earth, breeding on every continent except Antarctica and on many oceanic islands. Traditional nest sites are ledges on sea cliffs and rocky crags, but the species has adapted remarkably to human landscapes. Tall buildings, bridges, cathedrals, and power stations now serve as artificial cliffs, and city pigeons provide an abundant food supply. This flexibility has helped urban peregrine populations thrive across Britain and beyond.

## Nesting and young
Peregrines do not build a true nest; instead the female scrapes a shallow hollow on a cliff ledge or building and lays three to four reddish-brown eggs. Both parents share incubation over roughly a month, and the chicks, called eyases, hatch covered in white down. The young fledge at around six weeks but depend on their parents for weeks afterwards as they learn to hunt. Peregrines often mate for life and return to the same nesting site year after year.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/peregrine-falcon): Peregrine Falcon — wildlife guide.

## Recovery from near extinction
In the mid-20th century, peregrine populations crashed across Europe and North America as the pesticide DDT thinned their eggshells, causing them to break during incubation. After DDT was banned and captive-bred birds were released into the wild, numbers rebounded strongly. Today the peregrine is listed as Least Concern by the IUCN and is widely regarded as one of conservation's great success stories. Its comeback into city centres has made it one of the most watchable birds of prey.

## WARN work
WARN does not run a dedicated peregrine falcon programme — this guide is part of the World Animal Rescue Network's free educational library.

World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/peregrine-falcon): Peregrine Falcon — wildlife guide.

## How fast can a peregrine falcon fly?
In its hunting dive, or stoop, a peregrine falcon can exceed 380 km/h (240 mph), making it the fastest animal on the planet. In ordinary flapping flight it is much slower; the record speed applies only to the near-vertical plunge onto prey.

## What do peregrine falcons eat?
Peregrines are carnivores that feed almost entirely on other birds, such as pigeons, ducks, starlings, and waders, which they catch in mid-air. They occasionally take bats or small mammals, but birds caught on the wing make up the bulk of their diet.

## Where do peregrine falcons live?
Peregrine falcons are found on every continent except Antarctica, from Arctic tundra to tropical coasts. They nest on sea cliffs and rocky crags, and increasingly on tall buildings, bridges, and cathedrals in towns and cities.

## How long do peregrine falcons live?
Wild peregrine falcons can live up to about 15 years, though many die young in their first year. Birds that survive to adulthood and hold a good territory can breed for a decade or more.

## Are peregrine falcons endangered?
No. The peregrine falcon is listed as Least Concern by the IUCN. Populations collapsed in the mid-1900s because of the pesticide DDT, but after it was banned the species recovered strongly and is now widespread again.

## How big is a peregrine falcon?
The peregrine is a crow-sized raptor about 0.5 m long, weighing around 0.9 kg, with a wingspan of roughly 0.9 to 1.1 m (3 to 3.6 ft). As with most birds of prey, females are noticeably larger than males.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/ibis): Ibis — wildlife guide.

## One-line answer
An ibis is a long-legged wading bird with a distinctive long, down-curved bill used to probe mud and shallow water for food. The sacred ibis was revered in ancient Egypt.

## Introduction
An ibis is a long-legged wading bird with a distinctive long, down-curved bill used to probe mud and shallow water for food. The sacred ibis was revered in ancient Egypt. Ibises feed on insects, frogs, and small aquatic animals, nest in colonies, and often live around 20 years.

## Takeaway
An ibis is built for wetlands.

## Takeaway
Ibises are social birds that feed, roost, and nest in groups, often alongside herons, egrets, and storks.

## Takeaway
The sacred ibis was closely linked to the ancient Egyptian god Thoth, and vast numbers were mummified as offerings.

## The probing bill
An ibis is built for wetlands. Its long, slender, down-curved bill works like forceps, probing soft mud, shallow water, and grass for insects, worms, frogs, and small fish that it locates largely by touch. This lets ibises feed in murky water where sight-hunting birds struggle.

## Colonies and flight
Ibises are social birds that feed, roost, and nest in groups, often alongside herons, egrets, and storks. In flight they alternate flapping with gliding and often travel in long lines or V-formations between feeding and roosting sites.

## Sacred history
The sacred ibis was closely linked to the ancient Egyptian god Thoth, and vast numbers were mummified as offerings. Although it no longer breeds along the Nile, it remains widespread across sub-Saharan Africa and has formed feral populations in parts of Europe.

## Habitat and status
Ibises live around wetlands, floodplains, farmland, and even city parks, adapting well to landscapes shaped by people. Most species are common, and the sacred ibis is listed as Least Concern, though wetland drainage threatens some of their rarer relatives.

## WARN work
WARN does not run a dedicated ibis programme — this guide is part of the World Animal Rescue Network's free educational library. The ibis is currently widespread and not globally threatened, and this guide helps readers understand the pressures that can change that. Building public understanding of species like the ibis supports the broader conservation awareness that underpins WARN's partner-led rescue work across its network.

The anglerfish is a deep-sea fish named for the glowing, fishing-rod-like lure that grows from its head and attracts prey in the darkness. The familiar deep-sea females have huge mouths and needle-like teeth, and their light comes from glowing bacteria living in the lure.

## Introduction
The anglerfish is a deep-sea fish named for the glowing, fishing-rod-like lure that grows from its head and attracts prey in the darkness. The familiar deep-sea females have huge mouths and needle-like teeth, and their light comes from glowing bacteria living in the lure. In some species the tiny male permanently fuses to the female's body, becoming a lifelong source of sperm.

## Takeaway
Deep-sea anglerfish have a modified spine that extends over the mouth and ends in a fleshy, glowing tip.

## Takeaway
Many anglerfish live in the cold, dark, high-pressure waters of the deep sea, where food is scarce.

## Takeaway
In several deep-sea species, males are tiny compared with the much larger females.

## The glowing lure
Deep-sea anglerfish have a modified spine that extends over the mouth and ends in a fleshy, glowing tip. The light is produced by symbiotic bacteria living inside the lure, an example of bioluminescence. By wiggling this lure in the dark, the anglerfish draws curious prey close to its waiting jaws.

## Built for the deep
Many anglerfish live in the cold, dark, high-pressure waters of the deep sea, where food is scarce. They have enormous mouths, expandable stomachs, and long, inward-curving teeth that let them swallow prey nearly as large as themselves. Slow metabolisms help them survive long gaps between meals.

## Extreme reproduction
In several deep-sea species, males are tiny compared with the much larger females. A male finds a female using smell, bites onto her body, and in some species permanently fuses to her, sharing her bloodstream and becoming little more than an attached source of sperm. This ensures a mate is always available in the vast, empty deep.

## Habitat and range
Anglerfish are found in oceans worldwide, with many of the famous lured species living far below the sunlit zone. Some relatives, such as the shallow-water monkfish, live on the seafloor and are caught for food. Because deep-sea species are so remote, most are not considered threatened.

World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/anglerfish): Anglerfish — wildlife guide.

## Why does an anglerfish glow?
An anglerfish glows because of bioluminescent bacteria living in the lure on its head. The light attracts prey in the dark deep sea, drawing it close enough for the anglerfish to snap up.

## What does the anglerfish use its lure for?
The lure is a built-in fishing rod. By dangling and wiggling the glowing tip, the anglerfish entices curious prey toward its mouth, then ambushes it with a quick gulp.

## Do male and female anglerfish fuse together?
In some deep-sea species, yes. The much smaller male bites onto the female and can permanently fuse to her body, sharing her blood supply and serving as a lifelong source of sperm.

## Where do anglerfish live?
Many anglerfish live in the deep ocean, often well below 1,000 m where sunlight cannot reach, although some relatives live on the seafloor in shallower coastal waters.

## What do anglerfish eat?
Anglerfish are carnivores that eat fish and invertebrates. Their large mouths and expandable stomachs let them swallow prey nearly as big as themselves, an advantage where food is scarce.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/blue-tang): Blue Tang — wildlife guide.

## One-line answer
The blue tang (Paracanthurus hepatus) is a vivid royal-blue reef fish with black markings and a bright yellow tail, best known as the character Dory from Finding Nemo. It lives on coral reefs across the Indo-Pacific, where it grazes mainly on algae.

## Introduction
The blue tang (Paracanthurus hepatus) is a vivid royal-blue reef fish with black markings and a bright yellow tail, best known as the character Dory from Finding Nemo. It lives on coral reefs across the Indo-Pacific, where it grazes mainly on algae. Growing to about 30 cm long and weighing up to 0.6 kg, it is a fast, agile swimmer that darts among coral for shelter. Blue tangs can live up to around 20 years.

## Takeaway
The blue tang is one of the most recognisable reef fish, with an oval, flattened body painted in brilliant royal blue, a bold black pattern often described as a painter's palette, and a striking yellow tail.

## Takeaway
Blue tangs are omnivores that feed mainly on algae, which they nibble from coral and rock throughout the day.

## Takeaway
The blue tang belongs to the surgeonfish family, named for the sharp, scalpel-like spines set on either side of the base of the tail.

## Appearance and colour
The blue tang is one of the most recognisable reef fish, with an oval, flattened body painted in brilliant royal blue, a bold black pattern often described as a painter's palette, and a striking yellow tail. Its colour can shift with mood and time of day, deepening or fading depending on the fish's condition and stress level. Juveniles start out bright yellow and gradually gain the blue adult colouring as they grow. This eye-catching pattern has made the species a favourite in aquariums and a star of the cinema screen.

## Diet and feeding
Blue tangs are omnivores that feed mainly on algae, which they nibble from coral and rock throughout the day. By grazing on fast-growing algae they help keep reef surfaces clear, giving corals room to grow. They also take plankton drifting in the water column, and in captivity they will accept a mixed diet of plant and animal foods. Their small mouths and fine teeth are well suited to scraping and picking at the reef.

## The tang's defensive spines
The blue tang belongs to the surgeonfish family, named for the sharp, scalpel-like spines set on either side of the base of the tail. These spines normally lie flat in a groove but can be flicked out to slash at a rival or predator, and in this species they may carry a mild venom that adds sting to the wound. When threatened, a blue tang can also play dead, lying on its side and staying motionless until the danger passes. Together these defences help a fairly small fish survive on a crowded, predator-rich reef.

## Swimming and behaviour
Blue tangs are fast, agile swimmers, cruising the reef at speeds of up to around 10 km/h (6 mph) and darting into coral crevices at the first sign of danger. They propel themselves mainly with their pectoral fins, which gives them precise control for hovering and turning among the branching coral. Young fish and adults often gather in loose groups that move over the reef together, offering safety in numbers. At night they wedge themselves into cracks in the coral to rest, out of reach of hunting predators.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/blue-tang): Blue Tang — wildlife guide.

## Reproduction and life cycle
Blue tangs gather to spawn in groups, releasing eggs and sperm into the water where fertilisation takes place. The tiny eggs float with the plankton, and the larvae drift in open water before settling onto a reef and taking on their juvenile colours. On the reef they can live for up to around 20 years, a long life for a fish of their size. Because they are so difficult to breed in captivity, most blue tangs in the aquarium trade are still caught from the wild.

World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/blue-tang): Blue Tang — wildlife guide.

## Is the blue tang the fish from Finding Nemo?
Yes. The blue tang is the species behind Dory, the forgetful blue fish in Finding Nemo and Finding Dory. Its royal-blue body and yellow tail make it instantly recognisable.

## What do blue tangs eat?
Blue tangs are omnivores that feed mainly on algae, which they nibble from coral and rock. They also eat plankton from the water, and their grazing helps keep reef surfaces clear for corals.

## How big do blue tangs get?
Blue tangs grow to about 30 cm (12 inches) long and weigh up to around 0.6 kg. They are a medium-sized reef fish with a flattened, oval body.

## Are blue tangs dangerous?
They are not aggressive, but they carry sharp, scalpel-like spines at the base of the tail that can deliver a painful, mildly venomous cut. These spines are used in defence, so the fish should be handled with care.

## How long do blue tangs live?
Blue tangs can live for up to around 20 years, a long lifespan for a reef fish of their size. They are slow to mature and difficult to breed in captivity.

## Where do blue tangs live?
Blue tangs live on coral reefs across the Indo-Pacific, from East Africa to the reefs of the western Pacific. They stay close to branching coral, which offers both food and shelter from predators.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/hammerhead-shark): Hammerhead Shark — wildlife guide.

## One-line answer
Hammerhead sharks are a family of coastal and open-ocean sharks (Sphyrnidae) instantly recognised by the flattened, hammer-shaped head, or cephalofoil, that spreads their eyes and sensory organs wide apart. Species range from under a metre to more than 6 m long, with large individuals weighing around 230 kg.

## Introduction
Hammerhead sharks are a family of coastal and open-ocean sharks (Sphyrnidae) instantly recognised by the flattened, hammer-shaped head, or cephalofoil, that spreads their eyes and sensory organs wide apart. Species range from under a metre to more than 6 m long, with large individuals weighing around 230 kg. They swim through warm seas worldwide, hunting fish, squid and rays, and can live 20 to 30 years or more. The great hammerhead is listed as Critically Endangered.

## Takeaway
The wide, flattened head that gives these sharks their name is called a cephalofoil, and it is more than an odd silhouette.

## Takeaway
Hammerheads are carnivores that feed on bony fish, squid, octopus, crustaceans and other sharks, but they are best known for hunting stingrays.

## Takeaway
The family Sphyrnidae contains around nine species, and they vary enormously in size.

## The hammer-shaped head
The wide, flattened head that gives these sharks their name is called a cephalofoil, and it is more than an odd silhouette. Spacing the eyes far apart gives the shark a broader field of vision, while the underside is packed with electroreceptors called ampullae of Lorenzini that detect the faint electrical signals of buried prey. Sweeping the head from side to side lets a hammerhead scan the seabed like a metal detector. The shape also acts as a hydrofoil, helping the shark bank and turn sharply as it swims.

## Hunting and diet
Hammerheads are carnivores that feed on bony fish, squid, octopus, crustaceans and other sharks, but they are best known for hunting stingrays. A hammerhead will pin a ray to the seabed with the edge of its head, then pivot to take bites from the disc. Many individuals seem largely unbothered by the venomous barbs of their prey, and rays recovered from their stomachs are sometimes studded with spines. Larger species hunt alone, cruising close to the bottom where their electrical sense works best.

## Size and species
The family Sphyrnidae contains around nine species, and they vary enormously in size. The small bonnethead reaches under a metre, while the great hammerhead can exceed 6 m and weigh in the region of 230 kg, making it one of the largest predatory sharks. The scalloped and smooth hammerheads fall between these extremes. Despite their formidable appearance, hammerheads pose little danger to people, and unprovoked bites are very rare.

## Where they live
Hammerheads swim through warm temperate and tropical waters around the world, along coastlines, over continental shelves and out into the open ocean. They are found from shallow lagoons and coral reefs to depths of several hundred metres. Some species, notably the scalloped hammerhead, gather in large schools around seamounts and offshore islands, particularly by day. These aggregations can number in the hundreds and are a famous sight for divers.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/hammerhead-shark): Hammerhead Shark — wildlife guide.

## Reproduction
Hammerheads give birth to live young rather than laying eggs, nourishing the developing pups through a placenta-like connection inside the mother. Litters range from around a dozen to more than 40 pups depending on the species. The newborns are miniature versions of the adults, with heads that are more rounded at birth and flatten as they grow. Coastal nursery areas in shallow water shelter the young from larger predators during their vulnerable first months.

## Why the great hammerhead is Critically Endangered
The great hammerhead is listed as Critically Endangered by the IUCN, and several other hammerhead species are also threatened. Their large fins are highly valued in the shark-fin trade, and the sharks are frequently caught both deliberately and as bycatch in commercial fisheries. Hammerheads are especially vulnerable because they are slow to mature and produce relatively few young. They also suffer very high stress levels when hooked, so many die even when released.

## WARN work
WARN does not run a dedicated hammerhead shark programme — this guide is part of the World Animal Rescue Network's free educational library. The hammerhead shark faces documented conservation pressure in the wild, which is why clear, sourced public information about it matters. Building public understanding of species like the hammerhead shark supports the broader conservation awareness that underpins WARN's partner-led rescue work across its network.

World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/hammerhead-shark): Hammerhead Shark — wildlife guide.

## Why do hammerhead sharks have such strange heads?
The wide, flattened head, called a cephalofoil, spreads the eyes and electrical sensors far apart. This gives the shark a wider field of vision and a better ability to detect prey hidden in the sand. The shape also helps the shark turn quickly as it swims.

## Are hammerhead sharks dangerous to humans?
Hammerheads look intimidating but rarely pose a threat to people. Unprovoked bites are extremely uncommon, and most encounters involve the shark simply swimming away. Only the largest species could realistically injure a swimmer, and they show little interest in humans.

## How big do hammerhead sharks get?
Size varies greatly by species. The small bonnethead stays under a metre, while the great hammerhead can exceed 6 m and weigh around 230 kg. This makes the great hammerhead one of the largest predatory sharks in the ocean.

## What do hammerhead sharks eat?
Hammerheads are carnivores that eat fish, squid, octopus, crustaceans and other sharks. They are particularly known for hunting stingrays, which they pin to the seabed with their broad heads. They often appear immune to the rays' venomous barbs.

## How long do hammerhead sharks live?
Hammerheads are long-lived sharks, typically reaching 20 to 30 years and sometimes more. Their slow growth and late maturity are part of why overfishing has hit their populations so hard, as they cannot replace their numbers quickly.

## Why are hammerhead sharks endangered?
The great hammerhead is Critically Endangered, mainly because of the shark-fin trade and heavy accidental capture in fisheries. Hammerheads mature slowly and have small litters, so populations recover slowly. They also die easily from the stress of being hooked, even when released.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/bull-shark): Bull Shark — wildlife guide.

## One-line answer
The bull shark (Carcharhinus leucas) is a stocky, aggressive coastal shark famous for swimming far up rivers and into freshwater lakes. It grows up to about 3.5 m (11 ft) long and 130 kg (290 lb), and hunts a wide range of prey in warm seas, rivers, and estuaries.

## Introduction
The bull shark (Carcharhinus leucas) is a stocky, aggressive coastal shark famous for swimming far up rivers and into freshwater lakes. It grows up to about 3.5 m (11 ft) long and 130 kg (290 lb), and hunts a wide range of prey in warm seas, rivers, and estuaries. Fast in short bursts, it can reach around 40 km/h (25 mph) and lives 16 to 25 years. The IUCN lists it as Vulnerable.

## Takeaway
Bull sharks are heavy-bodied and muscular, typically 2 to 3.5 m (7 to 11 ft) long and weighing up to about 130 kg (290 lb), with females larger than males.

## Takeaway
The bull shark is one of the very few sharks that can thrive in freshwater as well as the sea.

## Takeaway
Bull sharks are opportunistic carnivores with one of the broadest diets of any shark.

## Size and appearance
Bull sharks are heavy-bodied and muscular, typically 2 to 3.5 m (7 to 11 ft) long and weighing up to about 130 kg (290 lb), with females larger than males. They are grey above and pale below, with a short, broad, rounded snout that gives them their name and their pugnacious look. Their small eyes suggest they often rely on other senses in the murky water they favour. Powerful jaws and stout teeth let them tackle unusually large and varied prey for their size.

## Life in freshwater
The bull shark is one of the very few sharks that can thrive in freshwater as well as the sea. Special adaptations in its kidneys, gills, and other organs let it control the salt balance in its body, so it can swim far up rivers and into lakes. Bull sharks have been recorded thousands of kilometres up the Amazon and Mississippi and living in Lake Nicaragua. This ability lets them hunt and give birth in places most sharks can never reach.

## Hunting and diet
Bull sharks are opportunistic carnivores with one of the broadest diets of any shark. They eat bony fish, other sharks and rays, turtles, crustaceans, seabirds, and even dolphins, taking almost anything they can overpower. They often hunt in shallow, cloudy coastal water and river mouths, using surprise and sudden bursts of speed of up to about 40 km/h (25 mph). This adaptable appetite is part of why they succeed in so many habitats.

## Reproduction and young
Female bull sharks give birth to live young, usually producing litters of around one to a dozen pups after a gestation of roughly a year. They favour shallow, brackish estuaries and river mouths as nurseries, where the young are relatively safe from larger ocean predators. Newborn pups are about 70 cm long and are independent from birth. Bull sharks live for around 16 to 25 years in the wild.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/bull-shark): Bull Shark — wildlife guide.

## Encounters with people
Because bull sharks are large, bold, and often swim in the shallow, murky water where people swim, they are considered one of the shark species most likely to be involved in bites on humans. Their tolerance of rivers and estuaries brings them into contact with people far from the open sea. Serious incidents are still rare, and most bull sharks show little interest in people. Sensible caution in murky coastal and river water reduces the already low risk.

## Conservation status
The bull shark is listed as Vulnerable by the IUCN. Like many sharks it is slow to mature and produces relatively few young, so populations recover slowly from pressure. Overfishing, capture for fins and meat, and the loss of the coastal and estuary habitats it uses as nurseries all threaten its numbers. Protecting river mouths and limiting catches are key to keeping the species healthy.

World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/bull-shark): Bull Shark — wildlife guide.

## Can bull sharks live in freshwater?
Yes. Bull sharks are among the few sharks that can survive in freshwater. Special adaptations let them control their body's salt balance, so they swim far up rivers and into lakes.

## How big do bull sharks get?
Bull sharks grow up to about 3.5 m (11 ft) long and can weigh around 130 kg (290 lb). Females are typically larger and heavier than males.

## Are bull sharks dangerous to humans?
Bull sharks are considered one of the species most likely to bite people because they are large, bold, and share shallow, murky water with swimmers. Even so, serious incidents remain rare.

## What do bull sharks eat?
Bull sharks are opportunistic carnivores with a very broad diet, including bony fish, other sharks and rays, turtles, crustaceans, seabirds, and occasionally dolphins.

## How fast can a bull shark swim?
Bull sharks can swim in short bursts of up to about 40 km/h (25 mph). They use these bursts of speed to ambush prey in shallow, cloudy water.

## How long do bull sharks live?
Bull sharks live for around 16 to 25 years in the wild. Like many sharks they mature slowly, which makes their populations sensitive to overfishing.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/electric-eel): Electric Eel — wildlife guide.

## One-line answer
The electric eel (Electrophorus electricus) is a freshwater fish of South America famous for generating powerful electric shocks to stun prey and defend itself. Despite the name it is not a true eel but a knifefish, growing up to 2.5 m long and weighing around 20 kg.

## Introduction
The electric eel (Electrophorus electricus) is a freshwater fish of South America famous for generating powerful electric shocks to stun prey and defend itself. Despite the name it is not a true eel but a knifefish, growing up to 2.5 m long and weighing around 20 kg. It is a slow, undulating swimmer that lives in murky streams and pools and breathes air at the surface. Electric eels live about 15 years and are listed as Least Concern.

## Takeaway
Despite its name, the electric eel is not a true eel at all but a type of knifefish, more closely related to catfish and carp than to the eels of the sea.

## Takeaway
Most of the electric eel's body is packed with specialised cells called electrocytes, stacked like the cells in a battery.

## Takeaway
The electric eel is a carnivore that preys on fish, amphibians, and invertebrates.

## Not a true eel
Despite its name, the electric eel is not a true eel at all but a type of knifefish, more closely related to catfish and carp than to the eels of the sea. It gets its name from its long, cylindrical, eel-like body, which can reach 2.5 m in length. It swims slowly by rippling a long fin that runs along the underside of its body. This undulating motion lets it move forward or backward with equal ease through cluttered water.

## How it generates electricity
Most of the electric eel's body is packed with specialised cells called electrocytes, stacked like the cells in a battery. When the eel discharges, thousands of these cells fire at once, producing a jolt strong enough to stun prey or deter a predator. It also emits weaker pulses used for navigation and to sense its surroundings in murky water. This makes electricity central to both hunting and communication.

## Hunting and diet
The electric eel is a carnivore that preys on fish, amphibians, and invertebrates. It hunts by releasing high-voltage discharges that stun or immobilise nearby prey, then swallows the helpless animal whole. Weak electric pulses help it locate targets it cannot see in cloudy, sediment-filled water. Because its eyesight is poor, it depends heavily on its electrical sense to find food.

## Breathing air
Electric eels live in oxygen-poor waters and cannot rely on their gills alone, so they gulp air at the surface using a specialised, blood-rich lining in the mouth. They must surface every few minutes to breathe, and would drown if unable to reach the surface. This adaptation lets them survive in stagnant, muddy pools where many other fish could not. It also means they spend much of their life near the surface.

## Habitat and range
Electric eels are found in the murky freshwater streams, pools, and floodplains of northern South America, including the Amazon and Orinoco basins. They prefer slow-moving, muddy water with plenty of cover. This dim, sediment-rich environment suits an animal that hunts by electricity rather than sight. They spend most of their time near the bottom, rising only to breathe.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/electric-eel): Electric Eel — wildlife guide.

## Life and conservation
Electric eels live about 15 years in the wild. During the dry season, a male builds a nest of saliva into which the female lays her eggs, and he guards the developing young. The species is widespread across its range and is listed as Least Concern by the IUCN. Its remote, murky habitat has helped keep populations stable.

## WARN work
WARN does not run a dedicated electric eel programme — this guide is part of the World Animal Rescue Network's free educational library. The electric eel is currently widespread and not globally threatened, and this guide helps readers understand the pressures that can change that.

## Is an electric eel a real eel?
No. Despite its name, the electric eel is not a true eel but a knifefish, more closely related to catfish and carp. It earned the name from its long, eel-like body shape.

## How does an electric eel produce electricity?
Most of its body is filled with specialised cells called electrocytes, stacked like a battery. When thousands fire together, they release a powerful electric discharge used to stun prey and defend against predators, along with weaker pulses for navigation.

## What do electric eels eat?
Electric eels are carnivores that eat fish, amphibians, and invertebrates. They stun prey with high-voltage shocks and then swallow the immobilised animal whole.

## How big do electric eels get?
Electric eels can grow up to 2.5 m long and weigh around 20 kg, making them large among freshwater fish. Their long, cylindrical bodies are packed with electricity-producing cells.

## Do electric eels breathe air?
Yes. Electric eels live in oxygen-poor water and gulp air at the surface using a blood-rich lining in the mouth. They must surface every few minutes and would drown without access to air.

## How long do electric eels live?
Electric eels live about 15 years in the wild. They are widespread across northern South America and are listed as Least Concern.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/great-white-shark): Great White Shark — wildlife guide.

## One-line answer
The great white shark (Carcharodon carcharias) is a large predatory fish found in cool and temperate coastal waters worldwide. It grows to around 4 to 4.6 m (13 to 15 ft), with some individuals exceeding 6 m, and can weigh up to 1,100 kg (2,400 lb).

## Introduction
The great white shark (Carcharodon carcharias) is a large predatory fish found in cool and temperate coastal waters worldwide. It grows to around 4 to 4.6 m (13 to 15 ft), with some individuals exceeding 6 m, and can weigh up to 1,100 kg (2,400 lb). A powerful hunter of seals, sea lions, fish, and rays, it can swim in short bursts of up to 56 km/h (35 mph) and may live as long as 70 years. The IUCN lists it as Vulnerable.

## Takeaway
Great white sharks are the largest predatory fish on Earth, typically measuring 4 to 4.6 m (13 to 15 ft), though exceptional individuals exceed 6 m.

## Takeaway
Great whites are carnivores that feed mainly on seals, sea lions, fish, and rays, shifting toward larger marine mammals as they grow.

## Takeaway
Great whites have an extraordinary array of senses tuned for hunting in open water.

## Size and appearance
Great white sharks are the largest predatory fish on Earth, typically measuring 4 to 4.6 m (13 to 15 ft), though exceptional individuals exceed 6 m. Mature adults commonly weigh between 680 and 1,100 kg (1,500 to 2,400 lb), and some are heavier still. Their name comes from the stark white underside, which contrasts with a slate-grey back that camouflages them against the seabed when viewed from above. This countershading lets them approach prey from below almost unseen.

## Hunting and diet
Great whites are carnivores that feed mainly on seals, sea lions, fish, and rays, shifting toward larger marine mammals as they grow. They often attack from directly beneath their target, rushing upward in a single explosive strike that can briefly reach 56 km/h (35 mph). Rows of serrated, triangular teeth are continuously replaced throughout the shark's life, so a worn or broken tooth is quickly succeeded by a fresh one behind it. After a heavy meal, a great white can go weeks before needing to feed again.

## Senses and navigation
Great whites have an extraordinary array of senses tuned for hunting in open water. Special jelly-filled pores called the ampullae of Lorenzini detect the faint electrical fields produced by other animals, allowing the shark to sense prey even when it cannot see it. A keen sense of smell can pick up traces of blood diluted in vast volumes of seawater, and a sensitive lateral line registers pressure changes and movement nearby. Together these senses make the great white a formidable and precise predator.

## Habitat and range
Great white sharks live in cool and temperate coastal waters across the globe, from the coasts of South Africa and Australia to California and the Mediterranean. They favour productive areas near seal colonies, rocky reefs, and offshore islands, but they also undertake long migrations across open ocean. Satellite tracking has revealed individuals crossing entire ocean basins and diving to considerable depths. This wide, patchy distribution makes the species difficult to survey accurately.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/great-white-shark): Great White Shark — wildlife guide.

## Reproduction and growth
Great whites are slow to mature, with females often not breeding until around 30 years of age. They are ovoviviparous, meaning the young develop inside eggs that hatch within the mother, and pups are born live after a gestation thought to last roughly a year. Litters are small, usually a handful of pups, each already more than a metre long and independent from birth. This slow reproductive pace, combined with a lifespan of up to 70 years, means populations recover only very gradually from losses.

## Why it is vulnerable
The IUCN classifies the great white shark as Vulnerable, reflecting long-term declines in many regions. Accidental capture in fishing gear, targeted hunting for jaws and teeth, and the depletion of prey have all taken a toll, made worse by the species' late maturity and low birth rate. Great whites are effectively impossible to keep in aquariums, as they fare poorly in captivity and rarely survive long. Legal protection in countries such as South Africa, Australia, and the United States has become central to safeguarding the remaining population.

Great white sharks are long-lived and may reach around 70 years of age. They grow and mature slowly, with females often not breeding until roughly 30 years old.

## What do great white sharks eat?
Great white sharks are carnivores that feed on seals, sea lions, fish, and rays. Younger sharks eat mostly fish and smaller prey, switching to larger marine mammals as they grow bigger and stronger.

## Are great white sharks endangered?
Great white sharks are listed as Vulnerable by the IUCN, not yet endangered but at real risk. Accidental capture in fishing gear, targeted hunting, and declining prey, combined with their slow breeding, all threaten their numbers.

## Can great white sharks be kept in aquariums?
No. Great white sharks are effectively impossible to keep in captivity, as they fare very poorly in aquariums and rarely survive more than a short time. Most attempts have ended with the shark being released or dying, so there are no long-term captive great whites.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/ant): Ant — wildlife guide.

## One-line answer
Ants are small social insects of the family Formicidae, found almost everywhere on Earth except the far polar regions. Ranging from 1 to 13 mm depending on species, they live in highly organised colonies of dozens to millions of individuals, each with a queen, workers, and cooperative roles.

## Introduction
Ants are small social insects of the family Formicidae, found almost everywhere on Earth except the far polar regions. Ranging from 1 to 13 mm depending on species, they live in highly organised colonies of dozens to millions of individuals, each with a queen, workers, and cooperative roles. Famous for their strength and teamwork, ants can lift many times their own body weight and are one of the most successful animal groups on the planet.

## Takeaway
Ants are among the most social of all insects, living in colonies built around a strict division of labour.

## Takeaway
For their size, ants are astonishingly strong, and many species can carry objects many times their own body weight in their jaws.

## Takeaway
Ants rely heavily on chemical signals called pheromones to coordinate their colony.

## Colony life and castes
Ants are among the most social of all insects, living in colonies built around a strict division of labour. A colony centres on one or more egg-laying queens, supported by large numbers of sterile female workers who forage, build, and care for the young. Males exist mainly to mate, and a single colony can range from just a few dozen ants to several million. This teamwork lets a colony behave almost like a single organism.

## Strength and teamwork
For their size, ants are astonishingly strong, and many species can carry objects many times their own body weight in their jaws. By working together, columns of ants can move loads and overcome obstacles far beyond the ability of any individual. Some species even link their bodies together to form living bridges and rafts, allowing the colony to cross gaps and floods.

## Communication with scent
Ants rely heavily on chemical signals called pheromones to coordinate their colony. A forager that finds food lays a scent trail on the way home, and nestmates follow and reinforce it, which is why ants so often march in orderly lines. They also use touch and antenna-tapping to share information, and different scents can raise an alarm or identify intruders from another colony.

## Diet and foraging
Most ants are omnivores whose exact diet varies widely by species. Many feed on seeds, nectar, and the sugary honeydew produced by aphids, which some ants tend and protect like livestock. Others are hunters that scavenge or capture insects and small invertebrates. Leafcutter ants take a different path, harvesting leaves to grow an underground fungus that the colony then eats.

## Lifespan and the colony cycle
Lifespan varies enormously across the caste system. Worker ants may live only weeks to about a year, while a queen can survive for 15 years or more, laying eggs throughout her long life. New colonies begin when winged males and young queens leave the nest in a mating flight; after mating, a founding queen sheds her wings and starts a new colony largely on her own.

## Diversity and success
There are more than 12,000 known ant species, occupying nearly every land habitat from tropical rainforest to city pavements, and absent only from the coldest polar regions. This diversity, combined with their social organisation, makes ants one of the most successful groups of animals on Earth. As a group they are common and listed as Least Concern by the IUCN, though some individual species are far rarer.

World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/ant): Ant — wildlife guide.

## How much can an ant lift?
Ants are extremely strong for their size, and many species can carry objects many times their own body weight in their jaws. By cooperating, groups of ants can move loads far larger than any single ant could manage alone.

## How do ants communicate?
Ants communicate mainly through chemical scents called pheromones. A forager lays a scent trail to guide nestmates to food, which is why ants march in lines, and other scents can sound an alarm or identify intruders from rival colonies.

## How long do ants live?
It depends on their role. Worker ants generally live from a few weeks up to about a year, while queens are far longer-lived and can survive for 15 years or more, laying eggs throughout their lives.

## What do ants eat?
Most ants are omnivores, and their diet varies by species. Common foods include seeds, nectar, and the sugary honeydew from aphids, while some ants hunt other insects and leafcutter ants farm fungus on harvested leaves.

## How big can an ant colony get?
Colony size ranges enormously, from just a few dozen ants in small species to several million in large ones. Each colony is organised around one or more queens supported by many sterile female workers.

## Where do ants live?
Ants are found almost everywhere on land, from tropical rainforests and deserts to gardens and city streets, and are absent only from the coldest polar regions. With over 12,000 species, they are one of the most widespread animal groups on Earth.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/dragonfly): Dragonfly — wildlife guide.

## One-line answer
Dragonflies are fast, agile flying insects with long bodies, huge eyes, and two pairs of transparent wings. They are skilled aerial predators that catch other insects in mid-air, and they spend most of their lives as aquatic larvae before becoming adults.

## Introduction
Dragonflies are fast, agile flying insects with long bodies, huge eyes, and two pairs of transparent wings. They are skilled aerial predators that catch other insects in mid-air, and they spend most of their lives as aquatic larvae before becoming adults. Adult dragonflies usually live only a few weeks to a few months.

## Takeaway
Dragonflies are among the most agile fliers in the insect world.

## Takeaway
A dragonfly's huge compound eyes can each contain tens of thousands of lenses and wrap around much of its head, giving it nearly all-around vision.

## Takeaway
Most of a dragonfly's life is spent underwater as a larva, sometimes for a year or more, where it hunts aquatic insects, tadpoles, and even small fish.

## Masters of flight
Dragonflies are among the most agile fliers in the insect world. They can move each of their four wings independently, allowing them to hover, fly backward, and change direction instantly. This control makes them highly effective at catching other insects in mid-air, with a very high hunting success rate.

## Remarkable vision
A dragonfly's huge compound eyes can each contain tens of thousands of lenses and wrap around much of its head, giving it nearly all-around vision. This excellent sight helps it spot and track fast-moving prey while flying, and judge the path needed to intercept it.

## Life in water and air
Most of a dragonfly's life is spent underwater as a larva, sometimes for a year or more, where it hunts aquatic insects, tadpoles, and even small fish. When ready, the larva climbs out of the water, its skin splits, and the winged adult emerges. The adult stage lasts only weeks to a few months.

## Habitat and importance
Dragonflies live near fresh water such as ponds, lakes, rivers, and wetlands, where they breed. Because their larvae are sensitive to pollution, the presence of dragonflies is often a sign of healthy water. They also help control populations of mosquitoes and other small insects.

## WARN work
WARN does not run a dedicated dragonfly programme — this guide is part of the World Animal Rescue Network's free educational library. The dragonfly is currently widespread and not globally threatened, and this guide helps readers understand the pressures that can change that.

World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/dragonfly): Dragonfly — wildlife guide.

## How fast can a dragonfly fly?
Dragonflies are strong fliers and can reach speeds of around 50 km/h (30 mph) in short bursts. Their independent wing control also lets them hover and even fly backward.

## What do dragonflies eat?
Adult dragonflies are carnivores that catch flying insects such as mosquitoes, flies, and gnats in mid-air. Their aquatic larvae eat other water insects, tadpoles, and small fish.

## How long do dragonflies live?
Adult dragonflies usually live only a few weeks to a few months. They spend much longer as underwater larvae, sometimes more than a year, before becoming winged adults.

## Do dragonflies bite or sting?
Dragonflies do not sting, and they are harmless to people. A large one might pinch if handled, but they have no venom and pose no danger.

## Are dragonflies good for the environment?
Yes. Dragonflies help control mosquitoes and other small insects, and because their larvae need clean water, their presence is a good sign of healthy freshwater habitats.

## Why do dragonflies have such big eyes?
A dragonfly's large compound eyes give it nearly all-around vision, which helps it spot and track fast prey in flight. Each eye can have tens of thousands of tiny lenses.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/grasshopper): Grasshopper — wildlife guide.

## One-line answer
Grasshoppers are plant-eating insects famous for their powerful hind legs, which let them leap many times their own body length. They live in grasslands and fields, where they feed on leaves and stems, and many produce a chirping sound by rubbing body parts together.

## Introduction
Grasshoppers are plant-eating insects famous for their powerful hind legs, which let them leap many times their own body length. They live in grasslands and fields, where they feed on leaves and stems, and many produce a chirping sound by rubbing body parts together. Most grasshoppers live for about a year or less.

## Takeaway
Grasshoppers have large, muscular hind legs that store energy like a spring, letting them launch into leaps many times their own body length.

## Takeaway
Grasshoppers are herbivores that feed on grasses, leaves, and other plants using strong chewing mouthparts.

## Takeaway
Many grasshoppers produce a chirping or buzzing sound, often by rubbing a hind leg against a wing, a behavior called stridulation.

## Powerful jumpers
Grasshoppers have large, muscular hind legs that store energy like a spring, letting them launch into leaps many times their own body length. Jumping helps them escape predators quickly, and many species can also fly to cover longer distances. The legs are the grasshopper's most distinctive feature.

## Diet and feeding
Grasshoppers are herbivores that feed on grasses, leaves, and other plants using strong chewing mouthparts. Most cause little harm, but when conditions allow certain species to gather in huge numbers as swarming locusts, they can strip crops and become serious agricultural pests.

## Sound and senses
Many grasshoppers produce a chirping or buzzing sound, often by rubbing a hind leg against a wing, a behavior called stridulation. These calls are used mainly to attract mates. Grasshoppers hear through simple ear-like organs located on the body rather than the head.

## Life cycle and habitat
Grasshoppers develop through incomplete metamorphosis, hatching as small wingless nymphs that grow through several molts into winged adults. They are found in grasslands, meadows, and fields on most continents, and are an important food source for birds, reptiles, and other animals.

## WARN work
WARN does not run a dedicated grasshopper programme — this guide is part of the World Animal Rescue Network's free educational library.

World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/grasshopper): Grasshopper — wildlife guide.

## How far can a grasshopper jump?
Grasshoppers can leap around 20 times their own body length thanks to their powerful spring-like hind legs. For a human, that would be like jumping the length of several buses.

## What do grasshoppers eat?
Grasshoppers are herbivores that feed on grasses, leaves, and stems. Most eat small amounts, but swarming species known as locusts can damage crops over wide areas.

## How do grasshoppers make sound?
Many grasshoppers chirp by rubbing a hind leg against a wing, a process called stridulation. These sounds are mainly used by males to attract mates.

## What is the difference between a grasshopper and a locust?
Locusts are certain grasshopper species that can change behavior and form massive migrating swarms when crowded. Otherwise they are closely related plant-eating insects.

## How long do grasshoppers live?
Most grasshoppers live for about a year or less. They typically hatch in spring, mature over the summer, and die as colder weather sets in.

## Do grasshoppers bite?
Grasshoppers can give a small nip if handled, but they are harmless to people. They have no venom and rely on jumping to escape rather than biting in defense.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/firefly): Firefly — wildlife guide.

## One-line answer
Fireflies are winged beetles of the family Lampyridae, famous for the cold, glowing light they flash to attract mates on warm summer nights. Most measure about 1 to 2.5 cm long and fly slowly over meadows, woodland edges, marshes and gardens.

## Introduction
Fireflies are winged beetles of the family Lampyridae, famous for the cold, glowing light they flash to attract mates on warm summer nights. Most measure about 1 to 2.5 cm long and fly slowly over meadows, woodland edges, marshes and gardens. Adults live only around two to four weeks, though the predatory larvae can survive a year or more before maturing. Worldwide the group is common and listed as Least Concern.

## Takeaway
Despite the name, fireflies are not flies at all but soft-bodied beetles belonging to the family Lampyridae.

## Takeaway
A firefly's light comes from a chemical reaction in special cells in its abdomen, where a compound called luciferin reacts with oxygen.

## Takeaway
The flashing has one main purpose: bringing males and females together to breed.

## Not a fly but a beetle
Despite the name, fireflies are not flies at all but soft-bodied beetles belonging to the family Lampyridae. There are around 2,000 known species spread across much of the world, most active on warm, humid evenings. Adults are generally small, at roughly 1 to 2.5 cm long, with soft wing cases that cover membranous flight wings. In some species the females are wingless and stay on the ground, and these are often called glow-worms.

## How and why they glow
A firefly's light comes from a chemical reaction in special cells in its abdomen, where a compound called luciferin reacts with oxygen. This is 'cold light', producing almost no heat and making it one of the most efficient forms of light in nature. The insect can switch its glow on and off and control the rhythm of its flashes. Even the eggs and larvae of many species glow faintly, which is thought to warn predators that they taste unpleasant.

## Flash signals and finding a mate
The flashing has one main purpose: bringing males and females together to breed. Each species uses its own pattern of flashes, timed and coloured just so, allowing individuals to recognise their own kind in the dark. Typically flying males signal and waiting females answer with a matching flash. In some tropical regions huge numbers of fireflies famously synchronise their flashes, lighting up whole trees at once.

## From glowing larva to adult
Fireflies spend most of their lives as larvae rather than as the glowing adults we notice. The larvae are fierce carnivores that hunt snails, slugs and worms, often for a year or more, injecting prey with digestive fluids. After pupating, the adult emerges to live only about two to four weeks, its short life focused entirely on breeding. Many adult fireflies eat little or nothing at all, relying on the reserves built up during the larval stage.

## Habitat and where to see them
Fireflies favour damp, vegetated places such as meadows, forest edges, marshes and quiet gardens, where their larvae can find plenty of snails and slugs. They are most visible on warm, still nights in late spring and summer, usually near water or long grass. Because they need moisture and darkness, undisturbed habitat matters a great deal to them. A single warm evening in the right spot can reveal dozens flashing over a field.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/firefly): Firefly — wildlife guide.

## Status and threats
As a whole the family is common and listed as Least Concern, but many individual firefly populations are thought to be declining. Light pollution is a particular problem, because artificial glow drowns out the flashes they rely on to find mates. Loss of the damp meadows and wetlands they breed in, along with pesticide use, adds further pressure. Reducing outdoor lighting and protecting moist habitat are simple ways to help them.

## WARN work
WARN does not run a dedicated firefly programme — this guide is part of the World Animal Rescue Network's free educational library.

World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/firefly): Firefly — wildlife guide.

## Are fireflies flies?
No. Despite the name, fireflies are beetles in the family Lampyridae, not true flies. There are around 2,000 species worldwide.

## How do fireflies glow?
Fireflies glow through a chemical reaction in their abdomen, where a substance called luciferin reacts with oxygen. This produces 'cold light' with almost no heat, making it extremely efficient.

## Why do fireflies flash?
Fireflies flash mainly to attract mates. Each species has its own flash pattern, so males and females can recognise and find one another in the dark.

## How long do fireflies live?
Adult fireflies live only about two to four weeks, during which they focus on breeding. The larvae, however, can live for a year or more before becoming adults.

## What do fireflies eat?
Firefly larvae are carnivores that hunt snails, slugs and worms. Many adult fireflies eat little or nothing, living off energy stored during the larval stage.

## Why are fireflies disappearing in some areas?
Many firefly populations are declining because of light pollution, which masks their mating flashes, along with habitat loss and pesticide use. Reducing outdoor lighting and protecting damp habitat can help them recover.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/cockroach): Cockroach — wildlife guide.

## One-line answer
Cockroaches are flattened, fast-moving insects known for their toughness and ability to thrive in many environments. Most of the thousands of species live in the wild, but a few have become common household pests.

## Introduction
Cockroaches are flattened, fast-moving insects known for their toughness and ability to thrive in many environments. Most of the thousands of species live in the wild, but a few have become common household pests. They are omnivores that eat almost anything and can survive for weeks without food.

## Takeaway
Cockroaches have flat, flexible bodies that let them squeeze into tiny cracks, and they can move very quickly to escape danger.

## Takeaway
As omnivores, cockroaches eat almost anything organic, including plants, crumbs, grease, paper, and decaying matter.

## Takeaway
Only a small number of cockroach species are household pests, but those that are can contaminate food and trigger allergies in some people.

## Built for survival
Cockroaches have flat, flexible bodies that let them squeeze into tiny cracks, and they can move very quickly to escape danger. They are highly adaptable, tolerating a wide range of conditions and going for weeks without food. These traits have made them successful for hundreds of millions of years.

## Diet and behavior
As omnivores, cockroaches eat almost anything organic, including plants, crumbs, grease, paper, and decaying matter. Most species are active at night and prefer dark, warm, humid hiding places. They are social to a degree and often gather in groups, guided by chemical scent trails.

## Pests and ecology
Only a small number of cockroach species are household pests, but those that are can contaminate food and trigger allergies in some people. The great majority of cockroach species live outdoors in forests and other habitats, where they help recycle decaying plant material and serve as food for other animals.

## Life cycle
Cockroaches develop through incomplete metamorphosis, hatching from egg cases as small nymphs that look like wingless adults. They molt several times as they grow. Many females carry or hide a protective egg case called an ootheca, which holds multiple eggs.

## WARN work
WARN does not run a dedicated cockroach programme — this guide is part of the World Animal Rescue Network's free educational library. The cockroach is currently widespread and not globally threatened, and this guide helps readers understand the pressures that can change that.
