Chameleon

Chameleons 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, stereoscopic eyes; their very long, highly modified, rapidly extrudable tongues; their swaying gait; and crests or horns on their distinctively shaped heads.
