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

## Conservation across species
Bear conservation varies dramatically by species. American black bears recovered to over 800,000 through regulated hunting and forest regrowth. Giant pandas moved from Endangered to Vulnerable after decades of habitat protection and captive breeding. Polar bears face existential threat from Arctic sea ice loss. Spectacled bears are Vulnerable as Andean forest is cleared. Sloth bears are Vulnerable from habitat loss and human conflict. Coexistence strategies — bear-proof bins, electric fencing, compensation schemes — reduce conflict worldwide. This guide introduces the bear family; see WARN's sun bear, Andean bear and species-specific guides for detail.

## WARN work
WARN funds sun bear and moon bear rescue in Indonesia, Malaysia and Vietnam — countries where bile farming and the pet trade threaten Asian bears. This bear guide is free public education about all eight species and the welfare crisis facing bears in Asia.

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

## How many bear species are there?
Eight living species: American black bear, brown (grizzly) bear, polar bear, spectacled bear, Asiatic black bear, sloth bear, sun bear and giant panda.

## Which bear is the largest?
The polar bear is the largest — males can exceed 800 kg. Kodiak brown bears of Alaska rival polar bears in size. The sun bear is the smallest at 25–65 kg.

## Are bears endangered?
It depends on the species. American black bears are abundant (800,000+). Polar bears, sun bears and sloth bears are Vulnerable. Giant pandas recovered to Vulnerable from Endangered.

## What is bear bile farming?
Keeping bears in cages and extracting bile from the gallbladder for use in traditional medicine. Bile contains ursodeoxycholic acid, but synthetic alternatives exist. Farming is legal only in China; Vietnam banned extraction in 2005.

## Do all bears hibernate?
Most bears enter winter torpor — reduced metabolism in dens — but tropical species (sun bear, sloth bear, spectacled bear) do not. Polar bears do not hibernate, though pregnant females den to give birth.

## Where do bears live?
Bears inhabit North America, South America, Europe and Asia — from Arctic ice (polar bear) to Andean cloud forest (spectacled bear) to Southeast Asian rainforest (sun bear).


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

## One-line answer
Whales are cetacean mammals (~90 species) including baleen and toothed forms — from the blue whale to sperm whales and orcas; status ranges from recovering humpbacks to Critically Endangered vaquita and North Atlantic right whale.

## Introduction
Whales are fully aquatic mammals of the infraorder Cetacea, divided into baleen whales (Mysticeti) that filter krill and small fish, and toothed whales (Odontoceti) that include sperm whales, orcas and dolphins. Roughly 90 species range from the 30-metre blue whale — the largest animal ever known — to the 2.7-metre vaquita porpoise, Critically Endangered in the Gulf of California. Whales evolved from land mammals roughly 50 million years ago; they breathe air, nurse young with milk and many migrate thousands of kilometres seasonally. This page is the whale family hub — see WARN guides for humpback whale, blue whale, sperm whale and orca.

## Takeaway
Whales include baleen whales (blue, humpback, fin) and toothed whales (sperm, orca, beaked whales).

## Takeaway
The blue whale is the largest animal ever known — up to 30 metres and 200 tonnes.

## Takeaway
Commercial whaling devastated populations; many species are recovering under moratoria.

## Takeaway
Ship strikes, entanglement in fishing gear and ocean noise are major modern threats.

## Takeaway
WARN publishes species guides for humpback, blue, sperm whale and orca.

## Takeaway
All cetaceans are protected in varying degrees — many on CITES Appendix I.

## Baleen whales versus toothed whales
Cetaceans split into mysticetes — baleen whales with keratin filter plates — and odontocetes — toothed whales with echolocation. Baleen whales include blue, fin, humpback, minke and right whales. They gulp or skim plankton and small fish. Toothed whales include sperm whales diving beyond 2,000 metres, orcas hunting in pods, and beaked whales of the deep ocean.

Dolphins and porpoises are odontocetes — WARN's dolphin hub covers oceanic bottlenose and common dolphins separately from this whale overview. Size spans four orders of magnitude: blue whale hearts alone weigh 180 kg.

Understanding the split helps explain diet, diving behaviour and conservation — baleen whales face ship strikes in migration corridors; sperm whales accumulate pollutants in blubber.

## Migration, song and culture
Many baleen whales migrate between high-latitude feeding grounds and tropical breeding lagoons. Humpbacks travel up to 8,000 km annually and produce complex songs that evolve year to year. Sperm whale clans carry distinct click dialects passed culturally between generations.

Orcas form matrilineal pods with specialised hunting traditions — fish-eating residents versus mammal-hunting transients in the Pacific North-west. Such culture makes local population loss irreversible even when the species globally persists.

Whale watching generates billions in ecotourism revenue when conducted at respectful distances — a conservation incentive when migration routes are protected.


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

## Whaling history and modern threats
Twentieth-century industrial whaling killed an estimated three million whales, pushing blue whales from an estimated 350,000 to roughly 10,000–25,000 today. The 1986 International Whaling Commission moratorium halted commercial whaling for most species; humpbacks and fin whales have rebounded in many regions.

Modern threats include entanglement in ghost nets and active fishing gear, ship strikes in busy shipping lanes, ocean noise masking communication, plastic ingestion and climate change shifting prey distribution. The North Atlantic right whale numbers fewer than 350; the vaquita may be functionally extinct with fewer than ten individuals.

Japan, Norway and Iceland conduct limited commercial or research whaling under IWC objections or reservations — a continuing conservation controversy.

## Whales and people
Whales feature in creation stories from the Pacific North-west to Iceland. Today they are flagship species for marine protected areas and shipping speed limits. Reducing single-use plastic, supporting sustainable fisheries and advocating quieter oceans benefit whales and human food security alike.

Readers should explore WARN's humpback whale, blue whale, sperm whale and orca guides for species-level detail, population trends and regional conservation work.

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

## How many whale species are there?
Roughly 90 cetacean species including baleen whales, sperm whales, beaked whales, dolphins and porpoises. 'Whale' usually excludes dolphins in everyday speech but includes them scientifically in Cetacea.

## What is the biggest whale?
The blue whale — up to about 30 metres long and 200 tonnes, the largest animal known to have lived on Earth.

## Are whales endangered?
Many are. Blue, fin and humpback whales are recovering after whaling moratoria. North Atlantic right whale and vaquita are Critically Endangered. Status varies sharply by species.

## Is an orca a whale or a dolphin?
Orcas are toothed whales (Odontoceti) — the largest oceanic dolphins. WARN covers orcas in a dedicated guide linked from this whale hub.

## Why did whales almost go extinct?
Industrial whaling in the twentieth century killed millions for oil, meat and baleen. The 1986 IWC moratorium allowed many populations to begin recovery.

## Where can I read about specific whales?
WARN publishes guides for humpback whale, blue whale, sperm whale and orca, plus river dolphin pages for freshwater cetaceans.


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

## One-line answer
The grey wolf (Canis lupus) is a Least Concern pack-hunting canid of the Northern Hemisphere and wild ancestor of dogs — regionally extirpated in much of Europe and North America but recovering where reintroduced.

## Introduction
The wolf (Canis lupus) is the largest wild member of the dog family, native to North America, Europe and Asia. Wolves live in cooperative packs led by a breeding pair, hunting deer, elk, moose and smaller prey. They are the wild ancestor of domestic dogs. Globally the IUCN lists grey wolves as Least Concern, but regional populations were exterminated across much of western Europe and the lower 48 United States before reintroductions — notably Yellowstone — began recovery. WARN also publishes guides for the grey wolf and maned wolf as distinct pages. This hub covers wolves as a species complex.

## Takeaway
Grey wolves are the wild ancestor of all domestic dogs.

## Takeaway
Packs are family groups — usually a breeding pair and offspring.

## Takeaway
Wolves were eradicated from much of western Europe and the US before partial recovery.

## Takeaway
Yellowstone wolf reintroduction restored ecosystem balance via trophic cascade.

## Takeaway
WARN guides cover grey wolf and maned wolf separately.

## Takeaway
Conflict with livestock drives ongoing persecution despite legal protection in many countries.

## What is a wolf — and how is it different from a dog?
Grey wolves (Canis lupus) are wild canids — larger, longer-legged and narrower-chested than most dogs, with straight tails and upright ears. Genetic studies show dogs diverged from wolves roughly 20,000 to 40,000 years ago through domestication. Wolves retain fear of humans and vast territory requirements — hundreds of square kilometres per pack in some regions.

Subspecies and local names abound: timber wolf, tundra wolf, Arabian wolf, Mexican wolf. The maned wolf of South America is a separate species (Chrysocyon brachyurus) covered in WARN's dedicated maned wolf guide — not a true wolf despite the name.

Distinguishing wolf from coyote, jackal or large dog requires expert assessment — misidentification drives unnecessary killing.

## Pack life and hunting
Wolf packs are typically extended families: a dominant breeding pair and their offspring from several years. Packs hunt cooperatively, testing weak elk or deer through endurance chases. Single wolves can kill moose or bison in deep snow. Howling maintains contact across territory and may reduce conflict between neighbouring packs.

Pups are born in dens in spring; the pack feeds lactating mothers and later regurgitates meat for pups. Dispersing young adults seek new territory and mates — critical for genetic exchange between populations.

Where wolves were removed, deer and elk overbrowsing damaged riparian vegetation until reintroduction restored balance — the classic Yellowstone trophic cascade.

## Persecution, recovery and conflict
Centuries of bounties, poisoning and habitat loss eliminated wolves from Britain, Japan and most of western Europe and the contiguous United States. Legal protection under the US Endangered Species Act and EU Habitats Directive enabled recovery in parts of Spain, Italy, Scandinavia and the Rocky Mountains.

Livestock depredation remains the main conflict. Non-lethal tools — fladry, guard dogs, range riders, compensation schemes — reduce losses more sustainably than indiscriminate culling. Illegal poisoning still kills wolves and scavenging raptors.

Hunting seasons resume in some US states when populations exceed targets — a politically charged management debate.


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

## Wolves and people
Wolves loom large in folklore — from Little Red Riding Hood to the she-wolf of Rome. Today they divide opinion between rewilding advocates and ranchers. Science supports coexistence where governance is fair and non-lethal tools are funded.

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

## Are wolves endangered?
Globally Least Concern with roughly 300,000 wolves. Regional populations were extirpated and remain Endangered — Mexican wolf, red wolf — or recovering under protection.

## What is the difference between a wolf and a dog?
Wolves are wild Canis lupus — dogs are domestic descendants. Wolves fear humans, need vast territories and cannot be tamed like dogs.

## Do wolves attack people?
Wild wolf attacks on humans are extremely rare. Healthy wolves avoid people. Most incidents involve rabid animals or habituated wolves fed by humans.

## What is a wolf pack?
Usually a family — breeding pair and offspring — not a hierarchy of alphas fighting for dominance. Cooperation defines pack hunting and pup-rearing.

## Is the maned wolf a real wolf?
No. The maned wolf is a separate South American canid. See WARN's maned wolf guide.

## Where were wolves reintroduced?
Yellowstone National Park (1995) is the famous US example. Wolves also recolonised naturally in parts of Europe — France, Germany, Scandinavia.


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

## One-line answer
Turtles (order Testudines) are ~360 species of shelled reptiles — sea turtles, freshwater terrapins and land tortoises — many Vulnerable to Critically Endangered from trade, bycatch and habitat loss.

## Introduction
Turtles are reptiles of the order Testudines, protected by a bony shell fused to the spine and ribs. Roughly 360 species include sea turtles, freshwater terrapins and land tortoises. They appeared over 200 million years ago and survive on every continent except Antarctica. Many species live decades or centuries. Today turtles are among the most threatened vertebrate groups — hunted for meat and shells, killed as bycatch, and losing nesting beaches to development and climate change. WARN's sea turtle guide covers marine species in detail; this hub introduces turtles as a whole.

## Takeaway
Turtles include sea turtles, freshwater terrapins and land tortoises — one order, Testudines.

## Takeaway
The shell is part of the skeleton — not a removable coat.

## Takeaway
Sea turtles migrate thousands of kilometres between feeding and nesting beaches.

## Takeaway
WARN's sea turtle guide covers marine species; this hub covers all turtles.

## Takeaway
Plastic pollution, bycatch and egg poaching threaten sea turtles globally.

## Takeaway
Galápagos giant tortoises can live over 150 years.

## Sea turtles, terrapins and tortoises
All turtles share a shelled body plan but occupy different worlds. Sea turtles — green, loggerhead, leatherback, hawksbill and others — have flipper-like limbs and salt glands. Freshwater terrapins and river turtles inhabit ponds, rivers and wetlands on every continent except Antarctica. Tortoises are land specialists with domed shells and columnar legs — Galápagos giants among the longest-lived vertebrates.

Temperature during egg incubation determines sex in many species — a climate change concern as beaches warm and produce female-biased broods. Nesting females return to the same beaches where they hatched, making beach protection critical.

WARN publishes a dedicated sea turtle wildlife guide; this page orients readers searching 'turtle' before they choose marine or freshwater detail.

## Life history and migration
Sea turtle hatchlings scramble to the sea at night, guided by light horizons — artificial lighting on developed coasts disorients them. Decades later, mature females haul onto beaches to lay eggs in excavated nests. Leatherbacks dive deeper than 1,000 metres; green turtles graze seagrass meadows that store carbon.

Freshwater turtles bask on logs, omnivorously scavenging and controlling aquatic vegetation. Many hibernate in mud through winter. Tortoises graze arid land vegetation, storing water in bladders during drought.

Slow maturity — 20 to 30 years in some sea turtles — means populations recover slowly from mortality spikes.

## Threats and conservation
Roughly half of turtle species are threatened on the IUCN Red List. Sea turtles face bycatch in shrimp trawls and longlines, plastic ingestion mistaking bags for jellyfish, egg poaching on nesting beaches and fibropapillomatosis disease linked to pollution. Freshwater turtles are eaten and traded as pets; tortoises are collected for illegal wildlife markets — radiated tortoise of Madagascar is Critically Endangered.

Marine protected areas, turtle excluder devices on nets, dark-beach lighting ordinances and community nest protection programmes show measurable recovery — green turtle populations increased in some regions after decades of work.

CITES Appendix I covers most sea turtles and many freshwater species.


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

## Turtles and people
Turtles appear in mythology worldwide — carrying the world on their backs, symbolising longevity. Today they need dark nesting beaches, clean oceans and enforced trade bans. Supporting WARN's sea turtle appeal funds nest protection and bycatch reduction where partners operate.

Never buy tortoiseshell products — hawksbill shell trade remains illegal and drives poaching.

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

## How many turtle species are there?
Roughly 360 species in order Testudines — sea turtles, freshwater terrapins and land tortoises combined.

## What is the difference between a turtle and a tortoise?
Tortoises live on land with domed shells and stumpy feet. 'Turtle' often means sea or freshwater species in everyday speech. Scientifically all are testudines.

## Are sea turtles endangered?
Most sea turtle species are Endangered or Vulnerable. Leatherbacks and hawksbills face severe pressure from bycatch and trade. Green turtles recover where beaches are protected.

## How long do turtles live?
Many tortoises live 80–150 years. Sea turtles may live 50–80 years. Slow maturity delays population recovery.

## Why do sea turtles eat plastic?
Floating plastic bags resemble jellyfish — a common prey item. Ingestion causes blockages, starvation and death.

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

## One-line answer
Otters are 13 species of aquatic mustelids worldwide — from the Endangered giant otter of South America to the recovering sea otter of the Pacific; status ranges from Least Concern to Endangered.

## Introduction
Otters are semi-aquatic carnivorans of the weasel family (Mustelidae), subfamily Lutrinae. Thirteen species range from the giant otter of Amazonian rivers — the longest mustelid at up to 1.8 metres — to the sea otter of North Pacific kelp forests, a keystone predator that uses tools to crack shellfish. Otters have dense waterproof fur, webbed feet and sensitive whiskers for detecting prey underwater. Conservation status varies sharply: North American river otters are Least Concern after recovery, while the giant otter is Endangered and the hairy-nosed otter of South-east Asia is Endangered. This page is the otter family hub — see WARN guides for giant otter and sea otter.

## Takeaway
Otters belong to the weasel family — not seals or beavers despite shared aquatic habits.

## Takeaway
Sea otters are keystone predators in kelp forests — their loss allows sea urchin overgrazing.

## Takeaway
The giant otter is the longest mustelid and Endangered across Amazonian river systems.

## Takeaway
Pollution, fishing nets and habitat loss threaten river otters globally.

## Takeaway
WARN publishes guides for giant otter and sea otter.

## Takeaway
Otter fur trade historically devastated populations; legal protection enabled partial recovery.

## River otters, sea otters and giant otters
Otters divide into freshwater and marine specialists. River otters — Eurasian, North American, smooth-coated and spotted-necked otters — hunt fish, crayfish and amphibians in lakes, rivers and wetlands. They are playful, social in some species and occupy territories marked with spraint (scented droppings) on prominent rocks.

Sea otters (Enhydra lutris) live almost entirely at sea in North Pacific kelp forests, wrapping in kelp to sleep and using stones as anvils to break open sea urchins, clams and abalone. They lack the insulating blubber of seals, relying instead on the densest fur of any mammal — up to one million hairs per square inch.

The giant otter (Pteronura brasiliensis) of Amazonian and Pantanal rivers is a separate lineage — up to 1.8 metres long, living in family groups that hunt cooperatively. It is Endangered from gold mining pollution, overfishing and habitat loss. WARN's giant otter and sea otter guides cover these flagship species in detail.

## Adaptations for aquatic life
Otter bodies are streamlined for swimming: short limbs, webbed feet, muscular tails and nostrils and ears that close underwater. Whiskers detect prey movement in murky water. River otters can hold breath for several minutes; sea otters dive for food but surface frequently because their fur traps air for insulation.

Pup rearing differs by species. Sea otter mothers float with pups on their chests, grooming constantly to maintain buoyancy and warmth. Giant otter families share pup care within the group. River otter pups are born in holts — burrows or cavities — along riverbanks.

These adaptations make otters sensitive barometers of water quality. Pesticide runoff, mercury from gold mining and entanglement in fishing gear kill otters directly and remove prey.


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

## Threats and conservation
Historically, otter fur drove commercial hunting that eliminated sea otters from much of their range and reduced river otter populations across Europe and North America. Legal protection and reintroduction programmes recovered North American river otters and parts of the sea otter population, though the southern sea otter remains below historical numbers.

Today, giant otters face mercury from artisanal gold mining in the Amazon, conflict with fishermen and habitat fragmentation. Asian otters — smooth-coated, hairy-nosed and small-clawed — are trapped for the illegal pet trade and fur. Entanglement in fishing nets kills otters on every continent.

Wetland protection, clean-water regulation and anti-poaching patrols in protected areas are the most effective measures. Brazil and Colombia — WARN partner countries — hold giant otter populations needing intact river systems.

## Otters and people
Otters appear in folklore from Native American trickster tales to Japanese river spirits. Today they are popular in media — but wild otters are not pets. Social-media demand for Asian small-clawed otters as exotic pets drives illegal trapping with high mortality in transit.

Responsible engagement means supporting clean rivers, avoiding otter cafés and pet purchases, and learning about species-level conservation needs. Ecotourism that respects distance can fund habitat protection where giant otters persist in Brazil's Pantanal.

## How many otter species are there?
Thirteen recognised species in subfamily Lutrinae, found on every continent except Australia and Antarctica.

## What is the biggest otter?
The giant otter of South America — up to about 1.8 metres long, Endangered across much of its Amazonian and Pantanal range.

## Are sea otters endangered?
Sea otters are Endangered in parts of their range. The southern sea otter population remains below historical levels despite protection; northern populations have recovered more strongly.

## Why do sea otters hold hands?
Sea otters sometimes raft together in kelp, occasionally holding paws so they do not drift apart while sleeping — a behaviour popularised in media but genuinely observed in wild groups.

## Can otters be pets?
No. Wild otters need large aquatic territories, specialist diets and social structures. The illegal pet trade threatens Asian otter species.

## Where can I read about specific otters?
WARN publishes giant otter and sea otter wildlife guides linked from this otter hub page.


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

## One-line answer
Leopards are spotted Panthera cats of Africa and Asia — Vulnerable (Panthera pardus) — plus clouded leopards and snow leopards as distinct species covered in separate WARN guides.

## Introduction
Leopards are large spotted cats of the genus Panthera, found across Africa and much of Asia. The African and Indian leopard (Panthera pardus) is listed as Vulnerable by the IUCN, declining from habitat loss, prey depletion and conflict with livestock owners. Clouded leopards and snow leopards belong to separate lineages but share the leopard name in common English. Leopards are extraordinarily adaptable — surviving in rainforest, desert margins and suburban edges where prey persists. They are powerful climbers, often storing kills in trees beyond the reach of lions and hyenas. This page is the leopard family hub — see WARN guides for clouded leopard and snow leopard.

## Takeaway
The African and Indian leopard (Panthera pardus) is Vulnerable and declining.

## Takeaway
Clouded leopards and snow leopards are separate species — not subspecies of Panthera pardus.

## Takeaway
Leopards are the most widespread big cat — found from Senegal to Sri Lanka.

## Takeaway
They are exceptional climbers, often caching kills in trees.

## Takeaway
WARN guides cover clouded leopard and snow leopard in detail.

## Takeaway
Skin trade, prey loss and retaliatory killing are major threats.

## Panthera pardus and the leopard complex
The leopard most people picture — golden coat with black rosettes — is Panthera pardus, ranging across sub-Saharan Africa, the Middle East, India, South-east Asia and historically into parts of Europe. Nine subspecies are recognised, though taxonomy shifts with genetic studies. Melanistic 'black panthers' are leopards (in Africa and Asia) or jaguars (in the Americas) with increased dark pigment — not a separate species.

Clouded leopards (genus Neofelis) occupy South-east Asian rainforest with cloud-like spot patterns and the longest canine teeth relative to body size among cats. The snow leopard (Panthera uncia) inhabits Central Asian mountains — thick fur, long tail for balance and Endangered/Vulnerable status depending on assessment. WARN treats clouded leopard and snow leopard as dedicated species guides linked from this hub.

Understanding the split prevents confusion: 'leopard' in everyday speech may mean Panthera pardus, clouded leopard, snow leopard or even the colloquial 'panther' for melanistic individuals.

## Ecology and behaviour
Leopards are solitary, territorial carnivores hunting deer, antelope, wild pig, baboons and smaller prey. Night vision, stealth and explosive acceleration make them effective ambush hunters. In trees they rest safely and hoist kills — a 50 kg impala carried up a trunk demonstrates extraordinary strength.

Home ranges vary from 30 km² for females in prey-rich forest to over 400 km² for males in arid landscapes. Scent marking and scrape piles communicate occupancy. Females raise cubs alone in dense cover for roughly 18 months.

Where lions and tigers exist, leopards shift toward nocturnal activity and tree use — niche partitioning that lets multiple big cats coexist. In India and Pakistan — WARN partner regions — leopards enter human-dominated landscapes when natural prey declines, raising conflict.


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

## Threats and trade
Leopard populations are declining across much of range. Habitat fragmentation removes cover and prey. Snares set for bushmeat kill leopards incidentally. Retaliatory shooting and poisoning follow livestock losses — especially where governance is weak.

Illegal trade in leopard skins persists for ceremonial dress, decoration and traditional medicine in some regions. CITES Appendix I prohibits commercial international trade in all leopard species. Enforcement varies; a single skin can fetch thousands on black markets.

Clouded leopards face additional pressure from deforestation for palm oil and logging across Malaysia and Indonesia — WARN partner countries. Snow leopards lose prey to overgrazing and are killed in retaliation for livestock predation across Central Asia.

## Leopards and people
Leopards have lived alongside humans for millennia — feared, revered and depicted in art from ancient Egypt to Mughal miniatures. Today coexistence requires livestock protection (predator-proof pens, guard dogs), fair compensation schemes and protected corridors linking forest fragments.

Melanistic leopards — 'black panthers' — capture public imagination but face the same threats as spotted individuals. Ecotourism that values living leopards supports anti-poaching in reserves from Sri Lanka to South Africa.

Readers searching 'leopard' should explore WARN's clouded leopard and snow leopard guides for species-level detail on South-east Asian forest cats and Himalayan specialists.

## Are leopards endangered?
Panthera pardus is Vulnerable globally with declining populations. Clouded leopards are Vulnerable to Endangered; snow leopards are Vulnerable. Status varies by region and species.

## What is a black panther?
A melanistic leopard in Africa and Asia, or a melanistic jaguar in the Americas. Increased dark pigment produces a black coat; rosettes may still be visible in certain light.

## How is a clouded leopard different from a leopard?
Clouded leopards belong to genus Neofelis — separate from Panthera pardus. They inhabit South-east Asian forest with cloud-like spots and exceptionally long canines.

## Where do snow leopards live?
Central Asian mountains from the Himalayas to the Altai — high-altitude specialists covered in WARN's snow leopard guide.

## Why do leopards climb trees?
For safety from lions and hyenas, to rest and to cache kills beyond scavengers' reach. Leopards are among the strongest tree-climbing big cats.

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

## One-line answer
Crocodilians are ~26 species of large aquatic reptiles — crocodiles, alligators, caimans and gharials — with status from Least Concern to Critically Endangered; WARN covers saltwater crocodile and alligator in detail.

## Introduction
Crocodilians are large aquatic reptiles of the order Crocodilia, including true crocodiles, alligators, caimans and gharials. They appeared over 80 million years ago and survive today as apex predators in tropical and subtropical wetlands. Roughly 26 species range from the 7-metre saltwater crocodile — the largest living reptile — to the Critically Endangered Cuban crocodile with fewer than 4,000 individuals. Crocodilians regulate body temperature by basking and cooling in water; mothers guard nests and carry hatchlings to water in some species. This page is the crocodile family hub — see WARN guides for saltwater crocodile and alligator.

## Takeaway
Crocodilians include crocodiles, alligators, caimans and gharials — one order, Crocodilia.

## Takeaway
Alligators have broad U-shaped snouts; crocodiles have narrower V-shaped snouts.

## Takeaway
Saltwater crocodiles are the largest living reptiles — up to 7 metres.

## Takeaway
Habitat loss and hunting devastated populations before legal protection.

## Takeaway
WARN guides cover saltwater crocodile and alligator.

## Takeaway
Crocodilians are keystone wetland species — their loss disrupts entire ecosystems.

## Crocodiles, alligators and their relatives
True crocodiles (family Crocodylidae) include the saltwater crocodile of Australasia, Nile crocodile of Africa and American crocodile of the Neotropics. Alligators and caimans (family Alligatoridae) have broader snouts and slightly different jaw anatomy — the American alligator of the south-eastern United States and the Chinese alligator (Critically Endangered) are best known. Caimans inhabit Central and South America; the black caiman rivals saltwater crocodiles in size.

Gharials (Gavialis gangeticus) — fish-eating specialists with long thin snouts — are Critically Endangered in Indian and Nepalese rivers. Pakistan's Indus river system historically held gharials; WARN's gharial guide covers that species separately.

Distinguishing crocodile from alligator: when jaws close, a crocodile's fourth lower tooth remains visible outside the upper jaw; alligator snouts are wider and more U-shaped. This hub orients searchers before they choose WARN's saltwater crocodile or alligator guides.

## Ecology and parental care
Crocodilians are ectothermic — basking to warm, retreating to water to cool. They are ambush predators, exploding from water to seize prey at the edge. Diet shifts with size: hatchlings eat insects and fish; adults take mammals, birds and other reptiles.

Nest guarding is sophisticated for reptiles. Females build mound or hole nests, guard eggs against predators and in some species assist hatchlings to water. Temperature during incubation determines sex in many species — a climate change concern.

As apex predators, crocodilians regulate prey populations and create habitat heterogeneity through wallowing and nest mound construction. Wetland drainage, pollution and entanglement in fishing gear threaten populations even where hunting is controlled.


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

## Conservation and recovery
Commercial hunting for skins devastated crocodilian populations through the twentieth century. Legal protection, ranching programmes and CITES regulation enabled recovery for American alligators, Nile crocodiles in some regions and saltwater crocodiles in Australia.

Critically Endangered species persist on life support: Cuban crocodile, Philippine crocodile, Chinese alligator and gharial number in the low thousands. Habitat loss — dam construction, rice farming, mangrove clearance — removes nesting beaches and basking sites.

Human-crocodile conflict occurs where people fish and collect water at river edges. Non-lethal management — warning signage, exclusion fencing, community education — reduces retaliatory killing while respecting crocodilians' ecological role.

## Crocodilians and people
Crocodilians appear in mythology from ancient Egypt to Aboriginal Australia — symbols of power and creation. Today sustainable ranching supplies legal leather for luxury markets while funding habitat protection in some countries.

Illegal trade in live animals and skins persists. Tourist attractions that mishandle crocodiles for photos create welfare problems and dangerous habituation.

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

## How many crocodilian species are there?
Roughly 26 living species — crocodiles, alligators, caimans and gharials combined in order Crocodilia.

## What is the difference between a crocodile and an alligator?
Alligators have broader U-shaped snouts; crocodiles have narrower V-shaped snouts. When jaws close, a crocodile's lower fourth tooth remains visible.

## What is the largest crocodile?
The saltwater crocodile — verified specimens exceed 6 metres; unverified reports approach 7 metres. It is the largest living reptile.

## Are alligators endangered?
The American alligator recovered to Least Concern after protection. The Chinese alligator is Critically Endangered with fewer than 150 wild individuals.

## Do crocodiles care for their young?
Yes. Females guard nests, assist hatchlings to water and protect young for weeks or months — unusual parental investment among reptiles.

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

## One-line answer
Donkeys (Equus asinus) are domestic equids used worldwide for transport and companionship — their wild ancestor is Critically Endangered; millions are killed yearly for the ejiao skin trade.

## Introduction
The donkey (Equus asinus) is a domesticated equid descended from the African wild ass, used worldwide for transport, pack work and companionship. Roughly 50 million donkeys serve communities where motor vehicles cannot reach — carrying water, firewood and goods across arid and mountainous terrain. The wild ancestor — African wild ass (Equus africanus) — is Critically Endangered with fewer than 600 individuals in Eritrea, Ethiopia and Somalia. Donkeys face a separate crisis: the global skin trade for ejiao, a gelatin used in traditional Chinese medicine, kills millions annually. WARN's working donkey guide covers welfare for animals in transport and agriculture.

## Takeaway
Donkeys are domestic equids — wild ancestor is the Critically Endangered African wild ass.

## Takeaway
Roughly 50 million donkeys support rural transport where vehicles cannot reach.

## Takeaway
The ejiao skin trade kills millions of donkeys annually — a global welfare crisis.

## Takeaway
Working donkeys need hoof care, shelter, water and rest — not disposable tools.

## Takeaway
WARN's working donkey guide covers welfare for animals in transport and agriculture.

## Takeaway
Donkeys are intelligent, social animals with strong bonds to companions.

## Domestic donkeys and wild ancestors
Domestic donkeys descend from the African wild ass, domesticated roughly 6,000 years ago in North-east Africa and the Middle East. Today breeds range from the miniature Mediterranean donkey to large American mammoth jacks used for mule production. Donkeys carry loads, pull carts, guard livestock against predators and serve as companions — particularly for horses, whose calm presence reduces equine stress.

The African wild ass — ancestor of the domestic donkey — persists in Critically Endangered populations in Eritrea, Ethiopia and Somalia. Hybridisation with feral donkeys and hunting threaten the last wild lineages. The onager and kiang are related wild equids of Asia.

This hub introduces donkeys as a group. WARN's working donkey guide addresses welfare for animals carrying loads in Pakistan, Colombia and other partner regions where donkeys remain essential infrastructure.

## Working donkey welfare
Working donkeys often lack basic care: overgrown hooves, ill-fitting tack, excessive loads and no access to shade or water. Heat stress, wounds from poor harnessing and colic from irregular feeding are common. Donkeys mask pain — stoic behaviour leads owners to overlook suffering until collapse.

Effective welfare programmes provide farriery, harness padding, load limits and owner education. Rest days, companion donkeys and shelter from sun and rain dramatically improve working lives. In Pakistan — a WARN partner country — donkeys transport goods in urban and rural settings where veterinary access is limited.

Donkeys are not small horses: they need lower-sugar diets, careful parasite management and patient handling. Fear-based training creates dangerous animals; positive reinforcement builds cooperative working partners.


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

## The ejiao skin trade crisis
Ejiao is a gelatin extracted from donkey skins, used in traditional Chinese medicine and cosmetics. Demand surged in the 2010s, triggering mass slaughter across Africa, South America and Asia. Countries including Burkina Faso, Niger and Kenya banned donkey export after local populations collapsed.

The trade kills animals inhumanely — stolen, transported long distances without food or water, slaughtered for skin while meat is discarded. Rural communities lose essential transport overnight. Illegal smuggling routes persist through borders with weak enforcement.

Campaigns for synthetic alternatives, CITES listing proposals and national export bans are conservation and welfare priorities. Consumers can refuse ejiao products and support donkey welfare charities operating farriery clinics.

## Donkeys and people
Donkeys appear in biblical narrative, Aesop's fables and rural economies on every continent. They are patient, intelligent and form strong pair bonds — separating companions causes measurable distress.

Responsible ownership means veterinary access, appropriate nutrition, hoof trimming every six to eight weeks and retirement rather than disposal when working life ends. Supporting WARN's working animal appeals funds farriery and harness repair where partners operate alongside horse welfare programmes.

## How many donkeys are there in the world?
Roughly 50 million domestic donkeys worldwide, concentrated in Africa, Asia and Latin America where they provide essential transport.

## Are donkeys endangered?
Domestic donkeys are abundant but face the ejiao skin trade crisis. The African wild ass — their ancestor — is Critically Endangered with fewer than 600 wild individuals.

## What is ejiao?
A gelatin from donkey skins used in traditional Chinese medicine and cosmetics. Demand drives mass slaughter and export bans across Africa.

## How are donkeys different from horses?
Donkeys are separate equids with longer ears, different vocalisations (braying), stoic pain masking and dietary needs — they are not simply small horses.

## What do working donkeys need?
Clean water, shade, appropriate loads, well-fitted harnesses, hoof trimming every six to eight weeks, companion animals and rest days.

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

## One-line answer
Tapirs are four threatened species of forest herbivore in Asia and the Americas — all Endangered or Vulnerable — serving as seed dispersers; WARN covers the Malayan tapir in detail.

## Introduction
Tapirs are large herbivorous mammals of the family Tapiridae, distantly related to horses and rhinos. Four species survive: Malayan tapir of South-east Asia; Baird's, lowland and mountain tapirs of Central and South America. All are threatened — Endangered or Vulnerable — from deforestation, hunting and road collisions. Tapirs are 'gardeners of the forest', dispersing seeds in droppings across vast home ranges. Their short flexible proboscis grabs leaves and fruit. Malayan tapirs — black with a white saddle — are the largest and most distinctive. WARN's Malayan tapir guide covers that species in detail for Malaysia and Indonesia partner regions.

## Takeaway
Four tapir species survive — one in Asia, three in the Americas.

## Takeaway
All four are threatened — Endangered or Vulnerable on the IUCN Red List.

## Takeaway
Tapirs disperse seeds across forest — earning the nickname 'gardeners of the forest'.

## Takeaway
Malayan tapirs inhabit Malaysia and Indonesia — WARN partner countries.

## Takeaway
WARN's Malayan tapir guide covers the Asian species in detail.

## Takeaway
Road kills, hunting and deforestation are primary threats.

## Four species across two continents
The Malayan tapir (Tapirus indicus) — black with a white or grey saddle — is the only Asian species, ranging from Myanmar through Malaysia, Thailand and Indonesia. Baird's tapir (Tapirus bairdii) inhabits Central American forest from Mexico to Colombia. The lowland tapir (Tapirus terrestris) is the most widespread South American species; the mountain tapir (Tapirus pinchaque) is the smallest, restricted to Andean cloud forest.

All tapirs share a compact body, short legs, three toes on each hind foot and a flexible proboscis formed from the upper lip and nose. Young tapirs of all species wear spotted or striped coats that fade with age — camouflage in dappled forest light.

Tapirs belong to order Perissodactyla alongside horses and rhinos — an ancient lineage of odd-toed ungulates. Fossil tapirs once ranged across Europe and North America.

## Ecology and seed dispersal
Tapirs are mainly nocturnal browsers, eating leaves, shoots, fruit and aquatic vegetation. Home ranges span dozens of square kilometres — Malayan tapirs traverse lowland and hill forest, following fruiting cycles seasonally. Seeds pass through the gut and germinate in droppings far from parent trees, linking tapir survival to forest regeneration.

Tapirs swim well, using water to escape predators and cool down. Jaguars and tigers prey on tapirs where their ranges overlap. Low reproductive rate — one calf every two years — makes population recovery slow after hunting pressure.

As large herbivores, tapirs maintain forest structure by browsing and creating trails used by other species. Their loss allows vegetation shifts that reduce biodiversity.


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

## Threats and conservation
Deforestation for palm oil, logging, cattle ranching and infrastructure removes tapir habitat across Malaysia, Indonesia, Brazil and Colombia — all WARN partner regions. Hunting for bushmeat persists despite legal protection. Road kills fragment populations as highways cross forest — a growing threat as Asia and Latin America develop transport networks.

All four species are CITES Appendix I or II. Protected areas harbour tapirs but enforcement against hunting and snaring is weak in many reserves. Camera-trap surveys monitor populations; wildlife corridors link forest fragments.

Captive breeding supports reintroduction for Baird's tapir in some regions. Malayan tapir captive programmes operate in zoos worldwide while wild populations decline.

## Tapirs and people
Tapirs appear in indigenous folklore across the Amazon and Malay Peninsula — often as shy forest spirits. Today they are flagship species for rainforest protection: saving tapir habitat preserves jaguars, hornbills and thousands of plant species.

Ecotourism in the Pantanal, Amazon and Taman Negara can fund anti-poaching when conducted responsibly. Consumers can choose certified sustainable palm oil and support habitat appeals.

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

## One-line answer
'Panther' is a colloquial term — not one species — referring to melanistic leopards or jaguars, cougars (including Florida panther) or large cats generally; WARN covers cougar, jaguar and leopard in dedicated guides.

## Introduction
'Panther' is not a scientific species name. In everyday English it may mean a melanistic (black-coated) leopard or jaguar, the cougar (Puma concolor — officially 'panther' in Florida), or loosely any large cat. Melanistic leopards carry excess dark pigment but retain rosette patterns visible in certain light. In the Americas, 'black panther' usually means a melanistic jaguar. The Florida panther is an Endangered cougar subpopulation. This page is the panther search hub — see WARN guides for cougar, jaguar and leopard.

## Takeaway
'Panther' is a common name — not a distinct species in taxonomy.

## Takeaway
Black panthers in Africa and Asia are melanistic leopards (Panthera pardus).

## Takeaway
Black panthers in the Americas are usually melanistic jaguars (Panthera onca).

## Takeaway
The Florida panther is an Endangered cougar subpopulation.

## Takeaway
WARN guides cover cougar, jaguar and leopard separately.

## Takeaway
Melanistic cats face the same threats as normally coloured individuals.

## What people mean by 'panther'
'Panther' derives from Greek and Latin words for leopard but today refers to several distinct cats depending on region. In Africa and Asia, a 'black panther' is a melanistic leopard — Panthera pardus with increased dark pigment. Rosettes remain visible in direct light. Melanism occurs in roughly 11% of leopards in Malaysian forest — an adaptation that may aid nocturnal hunting in dense cover.

In Central and South America, 'black panther' usually means a melanistic jaguar — Panthera onca. Jaguars are heavier, with broader heads and more powerful bites than leopards. Melanistic jaguars occur in Amazonian rainforest where WARN partners work in Brazil and Colombia.

In North America, 'panther' often means the cougar (Puma concolor) — particularly the Florida panther subpopulation, Endangered with roughly 120–230 adults. This hub helps searchers who query 'panther' find the correct WARN species guide.

## Melanism and genetics
Melanism in leopards and jaguars is controlled by a mutation in the ASIP gene — increased production of dark pigment (eumelanin) over the typical golden background. It is not albinism or a separate species. Melanistic cubs can be born to spotted parents and vice versa.

Adaptive advantage is debated: melanistic coats may improve camouflage in dense forest and at night. In open savanna, spotted coats may remain more common. Melanistic individuals breed with spotted ones — the trait persists as a polymorphism rather than a separate lineage.

Media depictions — from Bagheera in The Jungle Book to wildlife photography — popularised 'black panther' without explaining the underlying biology. Conservation messaging must treat melanistic cats as leopards or jaguars facing habitat loss and trade — not mystical separate species.


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

## Cougar, jaguar and leopard — WARN guides
WARN publishes three guides covering cats commonly called panthers. The cougar guide covers Puma concolor — the wide-ranging American cat including the Endangered Florida panther. Cougars are not in genus Panthera — they cannot roar, purring instead.

The jaguar guide covers Panthera onca — the apex cat of Neotropical forest, Near Threatened, threatened by deforestation and conflict with ranchers in Brazil and Colombia. The leopard hub covers Panthera pardus plus links to clouded leopard and snow leopard guides.

Readers searching 'panther' should choose the guide matching their region and interest — American cougar, Neotropical jaguar or Afro-Asian leopard.

## Panthers and people
Panthers — whether melanistic leopards, jaguars or Florida cougars — face the same conservation pressures as their normally coloured counterparts. Habitat loss, prey depletion, retaliatory killing and illegal skin trade threaten all large cats.

The Florida panther illustrates recovery challenges: inbreeding depression in a tiny population required introducing Texas cougars to restore genetic diversity. Highway collisions remain a leading cause of death.

Supporting habitat protection and anti-poaching benefits every large cat — spotted or melanistic — in WARN partner countries and worldwide.

## Is a panther a real species?
No. 'Panther' is a colloquial term for melanistic leopards or jaguars, cougars (including Florida panther) or large cats generally — not a separate species in taxonomy.

## What is a black panther?
A melanistic leopard in Africa and Asia, or a melanistic jaguar in the Americas. Increased dark pigment produces a black coat; rosettes may remain visible.

## What is the Florida panther?
An Endangered cougar (Puma concolor) subpopulation in Florida — roughly 120–230 adults — threatened by habitat loss and road collisions.

## Are black panthers endangered?
They are leopards or jaguars — Vulnerable or Near Threatened depending on species and region. Melanism does not change conservation status.

## Panther vs jaguar vs leopard?
Jaguars are American Panthera onca; leopards are Afro-Asian Panthera pardus; cougars are American Puma concolor. 'Panther' may refer to any of these depending on context.

World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/guinea-pig): Guinea Pig — wildlife guide.

## One-line answer
The guinea pig (Cavia porcellus) is a domesticated South American rodent that must live with companions, needs daily vitamin C and spacious enclosures — not solitary confinement in small hutches.

## Introduction
The guinea pig is a domestic rodent descended from wild cavies of the Andean highlands, kept for food and companionship for more than 3,000 years. Cavia porcellus cannot survive alone in the wild — every pet guinea pig is a domestic animal requiring sheltered housing, unlimited hay, fresh vegetables and at least one compatible companion. They are prey animals with sensitive hearing and quick flight responses; rough handling and small cages cause chronic stress. WARN publishes this guide as free welfare education: guinea pigs are not starter pets for children who want a single animal in a corner cage.

## Takeaway
Guinea pigs are strictly social — single-guinea-pig keeping causes loneliness and stress.

## Takeaway
They cannot synthesise vitamin C and need fresh vegetables or supplements daily.

## Takeaway
Prey instincts mean they hide illness until it is advanced — weigh weekly.

## Takeaway
Wire-bottom cages and small pet-shop hutches cause foot sores and boredom.

## Takeaway
Descended from Andean cavies — not pigs and not from Guinea.

## Takeaway
WARN's twelve-breed library covers coat types, temperament and health by variety.

## From Andean livestock to family companion
Guinea pigs were domesticated in the Andes more than 3,000 years ago, long before European contact. Indigenous communities raised cavies for meat and ceremonial use at altitudes where larger livestock struggled. Spanish colonists brought them to Europe, where they became laboratory animals and fashionable pets. The name 'guinea pig' is misleading — they are rodents of the family Caviidae, not pigs, and their origin lies in South America rather than West Africa.

Every modern guinea pig is Cavia porcellus, a fully domestic species with no self-sustaining wild population. Releasing pet cavies outdoors is cruel and illegal in many countries — they lack survival skills and suffer predation, starvation and temperature extremes within days.

## Social needs and behaviour
Guinea pigs are herd animals that communicate through wheeks, purrs, rumble-strutting and subtle body language. Keeping a single cavy in isolation causes measurable stress: reduced feeding, over-grooming and heightened fear responses. Welfare codes in Britain and the EU recommend housing at least two compatible animals after careful introduction.

Boars (males) may fight without adequate space and enrichment; neutering and large enclosures reduce conflict. Sows (females) usually pair or group well. Bonded companions should not be separated casually — losing a cage-mate causes grief visible in appetite loss and vocal searching.

## Housing, diet and health
Minimum enclosure sizes in UK guidance start around 1.5 m² for two guinea pigs, with larger always better. Solid floors covered in absorbent bedding protect feet — wire mesh floors cause bumblefoot. Hideouts, tunnels and hay racks support natural foraging. Daily exercise on grass (in secure runs) or indoor floor time prevents obesity.

Unlimited timothy or meadow hay should form most of the diet, supplemented with guinea-pig pellets fortified with vitamin C, fresh vegetables (pepper, kale, parsley) and clean water. Scurvy from vitamin C deficiency causes painful joints, dental problems and death. Teeth grow continuously — dental malocclusion is common and needs veterinary trimming.


World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/guinea-pig): Guinea Pig — wildlife guide.

## Welfare pitfalls and responsible ownership
Pet shops still sell solitary guinea pigs in cages far below recommended size. Impulse purchases at Easter and Christmas flood rescues by spring. Classroom pets rarely receive weekend and holiday care. Breeding 'accidents' from mis-sexed pairs produce surplus animals with limited rehoming options.

Responsible ownership means adopting from rescues, neutering where appropriate, budgeting for exotic-veterinary bills and committing to five to seven years of daily care. Children should be supervised — guinea pigs are not toys and should never be grabbed around the middle. WARN advocates adoption over purchase and opposes breeding for colour when rescues are full.

## Explore guinea pig breeds on WARN
Coat type changes grooming workload dramatically — from low-maintenance Americans to daily-brushed Peruvians. WARN publishes a twelve-breed guinea pig library at /wildlife-guides/guinea-pig covering American, Abyssinian, Peruvian, Silkie, Teddy, Rex and more, each with temperament notes, typical weight, common health issues and responsible-care FAQs.

Use the library to match breed to household: long-coated varieties suit experienced owners with time to groom; smooth-coated types suit families who still provide companionship and space. Every breed shares the same social and dietary rules — coat length does not reduce the need for a companion or vitamin C.

World Animal Rescue Network (https://worldanimalrescuenetwork.org/wildlife-guides/guinea-pig): Guinea Pig — wildlife guide.

## Can guinea pigs live alone?
No. Guinea pigs are social prey animals and should live with at least one compatible companion after careful introduction. Single-guinea-pig keeping causes loneliness and stress in most cases.

## Why do guinea pigs need vitamin C?
Like humans, guinea pigs cannot synthesise vitamin C. Deficiency causes scurvy — painful joints, poor wound healing and dental disease. Fresh vegetables and fortified pellets are essential daily.

## How long do guinea pigs live?
With good diet, companionship and veterinary care, guinea pigs typically live five to seven years, sometimes longer. Lifespan shortens with poor housing, solitary keeping and untreated dental disease.

## Are guinea pigs good pets for children?
They can be suitable with adult supervision and proper setup — but they are not low-maintenance starter pets. They need daily care, companions, space and quiet handling. Classroom and holiday neglect is a common welfare failure.

## Where did guinea pigs come from?
Guinea pigs were domesticated in the Andean highlands of South America more than 3,000 years ago from wild cavy ancestors. They are not from Guinea and are not related to pigs.

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

## One-line answer
Hamsters are nocturnal cricetine rodents — Syrian hamsters must live alone; dwarf species may tolerate pairs. Wild Syrian hamsters are Vulnerable; pet welfare requires large enclosures, deep bedding and wheels with a straight back.

## Introduction
Hamsters are short-tailed rodents of the subfamily Cricetinae, popular as pets since the 1930s when a wild Syrian hamster litter was bred in captivity. Five species dominate the pet trade: the strictly solitary Syrian (Mesocricetus auratus), Campbell's and winter white dwarf hamsters (Phodopus), the tiny Roborovski and the long-tailed Chinese hamster. Wild Syrian hamsters are Vulnerable in their native range near Aleppo, Syria — habitat loss and agricultural intensification threaten the last populations. Pet hamsters need large cages, deep burrowing substrate, species-appropriate wheels and respect for nocturnal behaviour.

## Takeaway
Syrian hamsters must live alone — pairing causes fighting to serious injury or death.

## Takeaway
Wild Syrian hamsters are Vulnerable; the pet trade descends from a 1930 captive litter.

## Takeaway
Hamsters are nocturnal — daytime disturbance causes chronic stress.

## Takeaway
Wire wheels with rungs and small cages cause spinal curvature and bar chewing.

## Takeaway
Dwarf hamsters need narrow bar spacing and sand baths; species rules differ.

## Takeaway
WARN's twelve-type hamster library covers Syrians, dwarfs, Roborovskis and more.

## Wild origins and domestication
The Syrian or golden hamster (Mesocricetus auratus) was first discovered in Aleppo, Syria, in 1839 but not bred successfully until 1930, when a mother and pups were brought to Jerusalem and then to laboratories worldwide. Every pet Syrian descends from that small founder population. Wild Syrians inhabit arid steppe and farmland, emerging at night to forage and burrow — their IUCN status is Vulnerable as agriculture replaces habitat.

Dwarf hamsters — Campbell's, winter white, Roborovski — were imported later from Central Asia. Chinese hamsters (Cricetulus griseus) are a separate lineage with a longer tail and different social rules. Understanding wild ecology explains pet needs: burrowing depth, nocturnal activity and species-specific territory.

## Syrian versus dwarf — social rules
Syrian hamsters are strictly solitary after roughly eight weeks of age. Housing two together causes escalating aggression — even littermates fight to death when maturity arrives. Each Syrian needs its own enclosure with minimum floor space around 80 cm × 50 cm in UK guidance, plus vertical enrichment.

Some dwarf species tolerate same-sex pairs or small groups if introduced young and monitored constantly — sudden aggression requires permanent separation. Roborovskis are fast and rarely tolerate handling; Campbell's and winter whites hybridise in pet trade lines. Never assume one hamster guide fits all species.

## Enclosure, wheels and enrichment
Deep bedding — 20 cm or more — allows burrowing behaviour suppressed in shallow cages. Aspen or paper bedding suits most species; cedar and pine shavings release harmful phenols. Solid-surface wheels with a diameter of at least 28 cm for Syrians prevent spinal curvature; runged wire wheels cause foot injuries.

Hideouts, cork tunnels, scatter feeding and safe chews reduce stereotypic bar chewing. Cages marketed as 'starter kits' are almost always too small. Glass tanks with mesh lids or modular enclosures outperform traditional wire cages with shallow bases.


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

## Health, handling and welfare failures
Hamsters hide illness until advanced — wet tail diarrhoea, respiratory infection and dental overgrowth are common emergencies. Diabetes affects some Campbell's lines; avoid sugary treats. Females can become pregnant from eight weeks — mis-sexed pet-shop pairs produce unwanted litters.

Handling should be calm and low — scoop from below, never grab from above like a predator. Daytime waking for children causes stress and defensive biting. Classroom hamsters often die from holiday neglect. WARN advises adoption from rescues and rejects impulse purchases in tiny cages.

## Explore hamster breeds on WARN
Coat colour and species change temperament, speed and housing rules. WARN publishes a twelve-type hamster library at /wildlife-guides/hamster covering Syrian, teddy bear, golden, Campbell's dwarf, winter white, Roborovski, Chinese and more — each with origin, typical size, social rules, common health issues and welfare FAQs.

Use the library before buying: a Roborovski suits observers who enjoy watching fast desert behaviour; a Syrian suits owners who want occasional calm handling — but only with nocturnal respect. Every entry reinforces that wheels, bedding depth and solitary housing for Syrians are non-negotiable.

Yes. Hamsters are primarily active at night. Daytime disturbance, classroom display and bright daytime handling cause chronic stress.

## What wheel size does a Syrian hamster need?
At least 28 cm diameter with a solid running surface — larger is better. Small or runged wheels cause spinal curvature and foot injuries.

## Are wild hamsters endangered?
The wild Syrian hamster is Vulnerable on the IUCN Red List due to habitat loss in Syria and Turkey. Pet Syrians descend from captive-bred lines, not ongoing wild harvest.

## Can dwarf hamsters live together?
Some Campbell's, winter white and Roborovski hamsters tolerate same-sex pairs or groups if raised together, but sudden aggression requires permanent separation. Always have spare enclosures ready.

## Where can I read about hamster types?
WARN's hamster wildlife guide at /wildlife-guides/hamster links to a twelve-type library covering Syrians, dwarfs, Roborovskis, Chinese hamsters and coat varieties with species-specific welfare notes.


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

## One-line answer
Chickens (Gallus gallus domesticus) descend from Least Concern red junglefowl — the world's commonest bird, raised for meat and eggs; backyard companions need space, dust baths and predator-safe housing unlike industrial systems.

## Introduction
The domestic chicken descends from red junglefowl of South and South-east Asia, domesticated at least 8,000 years ago. More than 25 billion chickens alive at any moment make Gallus gallus domesticus the most numerous bird on Earth — raised for meat, eggs, cockfighting and backyard companionship. Wild red junglefowl remain Least Concern in forest edge habitat, but industrial broiler and layer systems impose rapid-growth genetics, crowded sheds and short miserable lives on billions annually. WARN's guide addresses honest welfare for backyard flocks, rescue hens and the contrast with factory farming.

## Takeaway
Chickens descend from red junglefowl — not a separate wild species.

## Takeaway
More chickens exist than any other bird; most live in intensive farming systems.

## Takeaway
Backyard hens need predator-proof runs, dust baths, perches and social groups.

## Takeaway
Ex-battery hens require gradual rehabilitation after cage confinement.

## Takeaway
Broiler breeds suffer leg disorders from rapid growth genetics.

## Takeaway
WARN's twelve-breed chicken library covers layers, bantams, heritage and show types.

## From junglefowl to global livestock
Red junglefowl (Gallus gallus) still inhabit forest edges from India to Indonesia — the IUCN lists them Least Concern, though hybridisation with feral domestic chickens threatens wild genetics in some regions. Humans selected junglefowl for egg production, fighting temperament and later meat yield over millennia. Multiple domestication events may have occurred across South and South-east Asia before chickens spread along trade routes to Africa, Europe and the Americas.

Modern industrial strains bear little resemblance to heritage breeds: broilers reach slaughter weight in six weeks; layers produce 300+ eggs annually in wire cages. These genetics prioritise production over welfare — skeletal and respiratory disease are built into many commercial lines.

## Natural behaviour and flock life
Chickens are social galliforms with a clear pecking order, dust bathing, sun bathing, foraging and roosting instincts. A hen naturally lays a clutch then broods — continuous laying in domestic strains is a human-selected anomaly maintained by removing eggs. Roosters crow at dawn; hens communicate with over 30 vocalisations including food calls and alarm notes.

Depriving chickens of perches, litter to scratch and space to flee causes feather pecking, cannibalism and stereotypic pacing. Free-range labels vary legally — true pasture access with shelter differs sharply from a pop-hole into a bare yard.

## Backyard flocks and companion care
Backyard hens suit owners who provide secure housing against foxes, badgers, hawks and dogs — buried wire, locked coop doors and covered runs are essential in Britain. Minimum space guidance recommends roughly one square metre per bird in the run plus sheltered roost space. Dust baths control parasites; mixed-grain feeding supplements layer pellets and fresh greens.

Ex-commercial hens rehomed from cage systems often arrive featherless and weak — they need gentle integration, calcium support and patience as feathers regrow. Cockerels are often unwanted due to crowing restrictions; rehoming centres struggle with surplus males from accidental hatches.


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

## Factory farming and welfare reform
Roughly 70 billion chickens are slaughtered annually for meat worldwide — the majority in crowded sheds with ammonia-rich air, dim lighting and no perches. Beak trimming reduces injury in stressed flocks but causes chronic pain when done without analgesia. Slaughter at six weeks means broilers are still chicks in behaviour — their bodies are adult-sized through selective breeding.

Cage-free and free-range egg systems improve on barren battery cages but still permit high stocking densities and early culling of male chicks in hatcheries. WARN does not operate poultry farms but publishes honest education so readers understand the gap between a garden hen and an industrial carcass.

## Explore chicken breeds on WARN
Heritage breeds preserve genetic diversity lost in industrial hybrids. WARN publishes a twelve-breed chicken library at /wildlife-guides/chicken covering Rhode Island Red, Sussex, Leghorn, Silkie, Orpington, bantams and more — each with origin, egg or meat purpose, temperament and backyard-welfare notes.

Choosing a breed should match climate, space and purpose: lightweight Leghorns lay prolifically; heavy Orpingtons suit cold climates; bantams need less space but remain full chickens in behaviour. The library helps adopters and smallholders select birds they can care for properly — not impulse Easter chicks discarded in autumn.

## WARN work
WARN publishes free education on animal welfare worldwide. Industrial poultry production is one of the largest-scale animal welfare crises on Earth — honest chicken guides help readers distinguish responsible backyard care from systems that treat sentient birds as units of production.

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

## Are chickens wild animals?
No. Domestic chickens (Gallus gallus domesticus) are a human-created livestock form descended from red junglefowl. Wild junglefowl remain in Asia and are listed Least Concern.

## How many chickens are there in the world?
More than 25 billion chickens are alive at any moment — the most numerous bird on Earth. The vast majority are raised for meat and eggs in farming systems.

## What do backyard chickens need?
Predator-proof housing, covered run space, perches, dust-bathing areas, fresh water, balanced feed and at least two hens for social company. Daily checks for injury, mites and egg binding.

## How long do pet hens live?
Heritage and backyard hens often live five to eight years with good care. Commercial layer strains are typically culled after one to two years when egg production declines.

## Why are broiler chickens a welfare concern?
Broilers are bred for rapid growth — reaching slaughter weight in about six weeks. Many suffer leg disorders, heart failure and respiratory disease because their skeletons and organs cannot support their body mass.

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

## One-line answer
Goldfish (Carassius auratus) are domesticated East Asian carp relatives needing filtered tanks of 150+ litres per fancy fish — not bowls; released fish become invasive ecosystem pests.

## Introduction
The goldfish is a domesticated carp relative bred from Prussian carp in China more than 1,000 years ago, now one of the world's most popular aquarium fish. Carassius auratus exists in hundreds of fancy varieties — comets, fantails, orandas, ranchus — selected for colour, fin shape and body form. Pet goldfish routinely outlive dogs when housed properly, yet are sold in unfiltered bowls that kill them within weeks. Feral goldfish released into ponds and rivers grow enormous, compete with native fish and spread disease — a serious invasive species problem in North America, Australia and Europe.

## Takeaway
Goldfish are not bowl fish — they need filtration, space and regular water testing.

## Takeaway
Fancy varieties suffer swim-bladder and buoyancy problems from selective breeding.

## Takeaway
Released goldfish grow large and damage native freshwater ecosystems.

## Takeaway
Never flush live fish — humane euthanasia or rehoming only.

## Takeaway
Common comets need ponds; fancies need gentle tank mates and pristine water.

## Takeaway
WARN's twelve-variety goldfish library covers comets, fantails, orandas and more.

## Domestication and fancy breeding
Goldfish domestication began in the Tang dynasty, selecting Prussian carp (Carassius gibelio complex) for red colouration — a lucky hue in Chinese culture. Centuries of breeding produced fantails, telescopes, bubble eyes, ranchus and dozens of morphs with altered finnage, eye shape and body depth. Each mutation carries welfare trade-offs: deep-bodied fancies struggle to swim; telescope eyes impair vision; wen growth on orandas traps bacteria without pristine water.

The common comet goldfish sold cheaply at fairs differs from fancy varieties in hardiness but still needs filtration and volume — not a vase on a windowsill.

## Aquarium requirements — beyond the bowl myth
Goldfish are high-waste fish — they produce ammonia that poisons them in unfiltered bowls within days. A single fancy goldfish needs roughly 150 litres minimum with external filtration rated for double the tank volume; comets need ponds as adults. Weekly partial water changes, gravel vacuuming and testing for ammonia, nitrite and nitrate are baseline care.

Temperature should remain stable — goldfish are temperate, not tropical. Sharp décor tears flowing fins; smooth plants and driftwood suit fancies. Tank mates must be peaceful and not nip fins — many tropical species outcompete slow fancies for food.

## Health, lifespan and common failures
Properly housed goldfish live 10 to 20 years or more — older than many dogs. Stunted growth in small bowls is organ damage, not a separate 'bowl size' species. Swim-bladder disorder, fin rot, ich and flukes reflect poor water quality or inappropriate diet — not inevitable goldfish traits.

Overfeeding and flake-only diets cause constipation and buoyancy problems. Soaking pellets, offering blanched peas and limiting treats improve digestion. Quarantine new fish before introducing to established tanks to prevent disease spread.


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

## Invasive ferals and never release
Goldfish released into lakes and rivers survive, breed and grow beyond aquarium size — feral populations in Australia, Canada and Britain uproot vegetation, increase turbidity and outcompete native species. 'Freeing' a pet fish is ecological vandalism and animal cruelty.

Humane options include rehoming to pond keepers, contacting aquarium societies or veterinary euthanasia — never flush, which causes chlorine drowning and sewage contamination. WARN treats goldfish welfare and invasive species as linked education themes.

## Explore goldfish breeds on WARN
Fancy morphs differ sharply in care difficulty. WARN publishes a twelve-variety goldfish library at /wildlife-guides/goldfish covering comet, common, fantail, oranda, ryukin, ranchu, pearlscale and more — each with body type, temperament, typical size, health risks and tank-size guidance.

Match variety to setup: comets and commons need ponds; delicate ranchus need pristine shallow tanks without aggressive tank mates. The library reinforces that every variety rejects bowl keeping and wild release.

## Can goldfish live in a bowl?
No. Goldfish need filtered tanks of at least 150 litres per fancy fish, with regular water changes and testing. Unfiltered bowls cause ammonia poisoning and stunted organ damage.

## How long do goldfish live?
With proper filtration, space and diet, goldfish often live 10 to 20 years or longer. Bowl-kept fish usually die within weeks or months from water quality failure.

## Can I release a goldfish into a pond or river?
Never. Released goldfish survive, breed and become invasive pests that damage native ecosystems. Rehome responsibly or consult a vet for humane euthanasia.

## What is the difference between a comet and a fancy goldfish?
Comets have single tails and streamlined bodies — hardier and needing pond space as adults. Fancies have altered bodies and fins — slower swimmers needing gentle tank conditions and pristine water.

## Why do fancy goldfish float upside down?
Swim-bladder disorder often reflects overfeeding, poor water quality or selective breeding for deep bodies. Improve diet, test water parameters and avoid breeding extremes that compromise welfare.

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

## One-line answer
Betta splendens is a Vulnerable labyrinth fish of South-east Asian rice paddies — males are territorial; pet bettas need heated filtered tanks of at least 15–20 litres, not unheated bowls or vases.

## Introduction
The Siamese fighting fish (Betta splendens) is a labyrinth fish native to shallow waters of Thailand and neighbouring countries, listed Vulnerable on the IUCN Red List as habitat loss, pollution and hybridisation with released ornamental strains threaten wild populations. Male bettas defend territories fiercely — a behaviour exploited in historic fighting pits and modern marketing that sells them in unheated vases as if they thrive alone in stagnant water. Captive lines show extreme finnage from selective breeding, but all bettas need heated, filtered tanks, gentle flow and enrichment — not flower vases on desks.

## Takeaway
Wild Betta splendens are Vulnerable — habitat loss and pollution threaten native range.

## Takeaway
Males fight to serious injury — never house two males together.

## Takeaway
Labyrinth organ allows air breathing but does not remove need for clean heated water.

## Takeaway
Unheated vases and 'betta bowls' cause immune suppression and early death.

## Takeaway
Long-finned show morphs are human-bred — wild fish are duller green-brown.

## Takeaway
WARN's twelve-morph betta library covers halfmoon, plakat, crowntail and more.

## Wild bettas and Vulnerable status
Wild Betta splendens inhabit shallow rice paddies, slow streams and floodplain pools in the Mekong basin — murky, warm, vegetation-rich water quite unlike a desktop vase. The IUCN lists the species Vulnerable: agricultural intensification, pesticide runoff and drainage of wetlands reduce habitat while ornamental releases hybridise wild genetics.

Wild males show shorter fins and green-brown cryptic colouration — spectacular red and blue show fish are generations of captive selective breeding. Conservation of wild bettas depends on protecting rice-field mosaic habitats, not only banning wild harvest (which captive breeding largely replaced).

## Territorial behaviour and tank mates
Male bettas evolved to defend bubble-nest territories — seeing another male triggers flaring, chasing and biting that continues until one is dead or removed. Females can be kept in carefully structured sorority tanks by experienced keepers but aggression still erupts — most households should keep one betta alone in a species tank.

Community tanks are possible with caution: avoid fin-nippers like barbs and fast swimmers that stress slow-finned males. Shrimp and snails often work; bright male guppies may be mistaken for rivals. Line-of-sight blocks with plants reduce stress from reflections.

## Heated tanks, filtration and enrichment
Bettas are tropical — room-temperature water in Britain causes chronic stress and susceptibility to fin rot and ich. A heater maintaining 24–28 °C and a gentle filter preventing ammonia buildup are baseline requirements. Minimum tank volumes of 15–20 litres give swimming space and stable parameters; larger allows live plants and hiding spots.

Bettas enjoy resting on broad leaves near the surface — their labyrinth organ supplements oxygen but does not excuse dirty water. Soft flow matters: strong filters blow fish against glass. Enrichment includes live or silk plants, caves and occasional mirror exposure for short exercise — not constant mirror stress.


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

## Pet trade myths and welfare failures
Marketing still sells bettas as vase fish that eat plant roots — a fiction causing starvation and ammonia burns. Carnivorous bettas need high-protein pellets and frozen foods, not roots. Cup display in shops causes chronic stress; buyers should select active fish with intact fins and clear eyes.

Breeding extreme finnage produces fish that struggle to swim — ethical keepers support plakat (short-fin) lines or provide shallow tanks with resting spots. WARN opposes fighting-fish culture and vase marketing equally.

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

## Can bettas live in a bowl without a heater?
No. Bettas are tropical fish needing heated, filtered water at 24–28 °C. Unheated bowls in temperate homes cause chronic stress, disease and shortened lifespans.

## Why can't two male bettas live together?
Male bettas are territorial fighters evolved to defend bubble-nest sites. Two males in one tank fight until one is seriously injured or killed.

## Are wild bettas endangered?
Betta splendens is Vulnerable on the IUCN Red List due to habitat loss, pollution and hybridisation with released ornamental fish in Thailand and neighbouring countries.

## Do bettas eat plant roots in vases?
No. This is a marketing myth. Bettas are carnivores needing protein-rich pellets and frozen foods. Vase keeping starves fish and poisons them with ammonia.

## What tank size does a betta need?
At least 15–20 litres with a heater, gentle filtration, hiding places and plants. Larger tanks are easier to maintain and reduce stress.
