Chameleons (family Chamaeleonidae) are a distinctive and highly specialized clade of lizards.
The approximately 160 species of chameleon come in a range of colors, including pink, blue, red, orange, turquoise, yellow, and green. They are distinguished by their zygodactylous feet; their separately mobile, stereoscopiceyes; their very long, highly modified, rapidly extrudable tongues; their swaying gait; and crests or horns on their distinctively shaped heads. Some species can change color, and many have a prehensile tail. Uniquely adapted for climbing and visual hunting, they are found in warm habitats that vary from rain forest todesert conditions
