# Chameleon — Facts, Threats & Conservation

*Chamaeleonidae*

> A chameleon is an arboreal lizard of the family Chamaeleonidae, with around 200 species, about half found only in Madagascar. They are known for independently moving eyes, a fast projectile tongue, gripping feet, a prehensile tail and colour change used mainly for communication and temperature control.

**IUCN status:** Varies by species; many threatened  ·  **WARN range:** Madagascar, Sub-Saharan Africa, Southern Europe, Middle East, South Asia

## Scientific classification
- **Kingdom:** Animalia
- **Phylum:** Chordata
- **Class:** Reptilia
- **Order:** Squamata
- **Suborder:** Iguania
- **Family:** Chamaeleonidae
- **Genera:** ~10-12 (e.g. Chamaeleo, Furcifer, Calumma, Brookesia)

## Conservation status
- **Status:** Varies by species across the ~200-species family. Many are of lower concern, but a substantial number of narrow-range species, especially in Madagascar and African montane forests, are assessed as threatened, some Critically Endangered. Habitat loss is the principal threat, with the pet trade affecting some species.
- **Population:** No family-wide estimate; assessed species by species on the IUCN Red List
- **Trend:** Declining for many species, driven mainly by habitat loss
- **Assessed:** Assessed per species; family-wide figure not applicable
- **CITES:** Most species listed on CITES Appendix II
- Because many chameleons depend on small areas of specialised forest, clearing that habitat can threaten an entire species at once, making forest protection central to their survival.

## Key facts: Chameleon
- Chameleons (family Chamaeleonidae) number around 200 species, roughly half of which live only in Madagascar.
- Their colour change mainly signals mood and regulates temperature, rather than hiding them from predators.
- Each eye moves independently for near-360° vision, then both lock forward for stereoscopic aim before a strike.
- The projectile tongue can reach prey in as little as 0.07 seconds and extend well beyond body length.
- Gripping, pincer-like feet and a prehensile tail make them superb climbers in trees and shrubs.
- Conservation status varies by species; habitat loss and collection for the pet trade threaten many, and most are CITES-listed.

## How chameleons change colour - and why
Chameleons change colour using layers of specialised skin cells. Beneath the pigment-bearing cells lie nanocrystal-packed cells called iridophores; by actively spacing or tightening these crystals, a chameleon shifts which wavelengths of light are reflected, sweeping its skin from greens and blues toward yellows, oranges and reds. Pigment movement adds further tones. Contrary to popular belief, the primary purpose is not camouflage. Colour change is chiefly a language: males flush bright, bold patterns to display dominance or court mates, and turn dark when submitting or stressed. It also helps with thermoregulation, as a chameleon can darken to absorb more warmth in cool conditions or pale to reflect heat. Many species do rest in greens and browns that blend with foliage, so background-matching plays a supporting role, but the showiest changes are about signalling and body temperature, not invisibility. The speed and vividness vary widely between species, with some of the most dramatic displays seen in larger Madagascan and African chameleons.

## Built for the branches: eyes, tongue and grip
Few animals are as specialised for ambush hunting in trees as a chameleon. Its eyes sit in cone-shaped, scaly turrets that rotate independently, giving an almost complete field of view so it can scan for insects and predators at once. Once prey is spotted, both eyes converge to judge distance with precise stereoscopic vision. Then comes the tongue: a muscular, spring-loaded structure that launches faster than the eye can follow, striking prey in as little as 0.07 seconds and, in small species, extending more than twice the body length. A sticky, suction-like tip secures the catch and reels it back. Underpinning all this is a body made for climbing. The toes are fused into opposing bundles, two against three, forming pincers that clamp around twigs, while the prehensile tail coils like a fifth limb for extra anchorage. Most chameleons move slowly and deliberately, sometimes rocking as they walk to mimic a leaf swaying in the breeze.

## Where chameleons live and what they eat
Chameleons are overwhelmingly Old World animals. Madagascar is their heartland, home to about half of all species, with many found nowhere else on Earth. The remainder occur across sub-Saharan Africa, with a single species reaching southern Europe and a few extending through the Middle East to India and Sri Lanka; introduced populations also persist in places such as Hawaii and Florida. They occupy habitats from rainforest and montane cloud forest to dry woodland and even semi-desert scrub, and a few tiny species live in leaf litter rather than trees. Most are insectivores, picking off grasshoppers, crickets, flies and other invertebrates, though the largest species will take small birds, lizards and even the occasional fruit or leaf. Reproduction varies: many lay eggs, burying clutches in soil, while some montane species give birth to live young. Lifespans differ by species, commonly spanning roughly three to about ten years, with smaller species tending to live shorter lives.

## Why chameleons are under pressure
There is no single conservation status for chameleons, because the family spans roughly 200 species with very different fortunes. Some are widespread and of low concern, while others, particularly narrow-range species in Madagascar and Africa's montane forests, are assessed as threatened or even Critically Endangered. The overriding problem is habitat loss: forests are cleared for farmland, fuel and timber, and because so many chameleons live only in small patches of specialised habitat, losing those forests can imperil an entire species at once. Collection for the international pet trade adds further pressure on some sought-after species, which is why most chameleons are listed on CITES Appendix II to regulate cross-border trade. Climate change compounds the risk for cool, high-altitude specialists with nowhere cooler to go. Because they depend so completely on intact forest, chameleons are useful indicators of habitat health: protecting the forests they need also safeguards countless other species that share those landscapes.

## Chameleon vs typical lizard: what sets chameleons apart
| Feature | Chameleon | Typical lizard |
| --- | --- | --- |
| Eyes | Move independently in turrets; near-360° vision | Move together; fixed forward field |
| Tongue | Projectile, strikes in ~0.07s, longer than body | Short; not projectile |
| Feet | Toes fused into opposing pincers for gripping | Separate clawed toes |
| Tail | Prehensile, used as a fifth limb | Usually not prehensile |
| Colour change | Active, for signalling and temperature | Limited or none in most species |
| Lifestyle | Mostly slow, arboreal ambush hunters | Often fast, ground-dwelling |

## What WARN does
World Animal Rescue Network does not currently run field projects specifically for chameleons, which live mainly outside WARN's five partner countries. This guide is part of WARN's free educational and awareness work, helping people understand and value lesser-known wildlife. The same pressures that threaten chameleons - especially habitat loss - also affect the animals WARN does protect, so supporting habitat and wildlife work has benefits that reach far beyond any single species.

If you would like to help, supporting WARN's habitat and wildlife work is a gentle way to stand up for the forests and the creatures, large and small, that depend on them.

## Frequently asked questions: Chameleon
### Why do chameleons change colour?
Chameleons change colour mainly to communicate and to regulate their temperature, not primarily to hide. By rearranging tiny light-reflecting crystals in their skin, they shift between greens, blues, yellows and reds. Bright, bold colours signal dominance or courtship, while dark tones often mean stress or submission. Darkening also helps them absorb warmth, and paling reflects heat. Background-matching plays only a supporting role.

### How fast is a chameleon's tongue?
Astonishingly fast. A chameleon can strike prey in as little as 0.07 seconds, with the tongue accelerating at well over 40 times the force of gravity - quicker than the human eye can follow. In smaller species the tongue can extend more than twice the body length. A sticky, suction-like tip grabs the insect, and powerful muscles reel the catch straight back to the mouth.

### Where do chameleons live?
Chameleons are Old World lizards found mainly in Madagascar and across sub-Saharan Africa. About half of all species live only in Madagascar. A single species reaches southern Europe, and a few extend through the Middle East to India and Sri Lanka. Introduced populations also persist in places such as Hawaii and Florida. They occupy rainforest, cloud forest, dry woodland and even semi-desert scrub.

### How many species of chameleon are there?
Around 200 chameleon species have been described, grouped into roughly 10 to 12 genera within the family Chamaeleonidae. They range dramatically in size, from a leaf-litter dweller barely the length of a fingernail to a lizard nearly 70 centimetres long. Scientists continue to describe new species, particularly in Madagascar and Africa, so the total tends to rise over time as research continues.

### What do chameleons eat?
Most chameleons are insectivores, ambushing grasshoppers, crickets, flies and other invertebrates with their high-speed projectile tongue. Larger species will also take small birds, lizards and other small vertebrates, and some occasionally eat plant material such as leaves and fruit. They hunt by sight, using independently swivelling eyes to spot prey, then locking both eyes forward to judge distance before striking.

### Are chameleons endangered?
It depends on the species. With around 200 species, status varies widely: some are widespread and of low concern, while many narrow-range species, especially in Madagascar and Africa's montane forests, are threatened or Critically Endangered. The main causes are habitat loss and, for some species, collection for the pet trade. Most chameleons are listed on CITES Appendix II to regulate international trade.
