Chameleon

Chameleon, family chamaeleonidae, are old world lizards that dwell in trees, except for the stump tailed chameleon, genus Brookesia, which lives mainly on the forest floor. Chameleons range from Africa and Madagaskar to southern Spain, India, and Sri Lanka. They are noted for their ability to change color in response to light, heat, and other stimull. The rang of colors is limited to shades of green, yellow, or brown. The males, in particular, often have horns, crests, of flaps on their heads.

The lizards range in length from les than 7.5 cm (3 in) for Brookesia to more than 60 cm (24 in) for some species of Chamaeleo. Chameleons have a long, flattened body and –except for the stump-tailed variety –a prehensile tail that serves as an extra limb. The hind foot has two toes on the inside and three on the outside; the forefoot has the opposite arrangement. The chameleon's protruding eyes are almost completely convert by eyelids, leaving only a narrow opening; the eyes can rotate independently in a complete hemisphere. The tongue, which may be longer than the body, is used to snare eat birds and small rodents. Chameleons are mostly oviparous, developing and hatching their eggs outside the body, but a few are ovoviviparous producing living young within the body.
