|Oustalet's Chameleon, Ambalavao, Madagascar|
They are a distinct clade of lizards. They have parrot-like zygodactylous feet, separately mobile and stereoscopic eyes, very long tongues they can flick out, a swaying gait, their prehensile tail, crests or horns on their strange-shaped heads, and many can change colour.
There are about 160 species, living in Africa, Madagascar, Spain and Portugal, across south Asia, Sri Lanka. They have been introduced to Hawaii, California and Florida, and are found in warm habitats that vary from rain forest to desert conditions. Chameleons are often kept as household pets.
Chameleons have long sticky tongues that they can fire out in a fraction of a second. They stretch up to twice their body size. Their eyes can move independently. The largest species is about 1.5 feet when fully grown. They are mainly insectivores, but they do take occasional smaller lizards.

Notes[change | change source]
- Zygodactyly: (birds) an arrangement with two toes facing forward (digits 2 and 3) and two back (digits 1 and 4); (chameleons) the feet are fused into a group of two and a group of three toes which oppose one another to grasp branches in a pincer-like arrangement. Zygodactyly is most common in arboreal species, particularly those that climb tree trunks or clamber through foliage.
- Eyes can focus and move independently.
- Their movement sways like leaves in the wind.
- Tail can hang onto branches
