Quick answer
Chameleons are a family of tree-dwelling lizards, most famous for changing color and for eyes that swivel independently to give nearly 360-degree vision. Found mainly in Africa and Madagascar, they catch insects with a sticky, projectile tongue that can extend longer than their own body. There are over 200 species, and color change is used as much for communication and temperature as for camouflage.

Biology
Chameleon (Chamaeleonidae) is classified as Reptile with conservation status Least Concern. Typical weight about 0.15 kg; lifespan around 3–10 years depending on species.
Ecology
Diet: Insectivore (mostly). Habitat: Forest, savanna, and scrub. Movement and social systems reflect those pressures.
People and this species
Learn before you travel or keep related pets. Wild individuals are not toys; captive care needs species-specific husbandry.

How they change color
Chameleons change color not mainly by pigment but by adjusting microscopic crystals in their skin that reflect different wavelengths of light. They shift color to communicate mood, attract mates, intimidate rivals, and regulate temperature, darkening to absorb heat. Camouflage is only part of the story.
Independent eyes
A chameleon's turret-like eyes move independently of each other, letting it scan in two directions at once for nearly 360-degree vision. When it spots prey, both eyes lock forward together to judge distance with precision before the tongue strikes.
The explosive tongue
A chameleon hunts by firing out a sticky-tipped tongue that can be longer than its entire body, striking prey in a fraction of a second with remarkable accuracy. Special gripping feet and a prehensile tail that curls around branches make it a slow but sure-footed climber.
Diversity and conservation
There are more than 200 chameleon species, around half of them found only on the island of Madagascar, from giants over half a meter long to tiny species smaller than a fingernail. While many are listed as Least Concern, deforestation and the pet trade threaten a number of the more specialized species.
Research notes
Figures for chameleons (Chamaeleonidae) come from field studies, museum records, and conservation assessments that do not always agree on exact averages. Prefer ranges over single-point claims, and check whether a source describes wild, captive, or mixed populations.
Practical takeaways
If you encounter chameleons in the wild, prioritise distance and local guidance. If you care for related domestic or captive animals, match diet and housing to species needs rather than generic pet advice. Share accurate status information (Least Concern) when discussing conservation.
