Most can change the colour of their [[skin]]s for [[camouflage]], or to signal [[mood]] to other chameleons. They are a [[clade]] of lizards. They have parrot-like zygodactylous feet,<ref>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. </ref> Their eyes are separately mobile and [[stereoscopy|stereoscopic]].<ref>Eyes can focus and move independently.</ref> Their very long tongues can flick out, and their movement sways like leaves in the wind. Their prehensile (grabbing) tail can hang onto branches and many can change colour. They eat insects. Chameleons have long sticky [[tongue]]s 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 larger species may take occasional smaller lizards and young birds.<ref>Dever, Jennifer 2007. Common Chameleon (PDF). usfca.edu.
