Chamaeleonidae

"Chameleons or chamaeleons (family Chamaeleonidae) are a distinctive and highly specialized clade of Old World lizards with 202 species described as of June 2015. These species come in a range of colors, and many species have the ability to change color.

Chameleons are distinguished by their zygodactylous feet; their very extensive, highly modified, rapidly extrudable tongues; their swaying gait; and crests or horns on their brow and snout. Most species, the larger ones in particular, also have a prehensile tail. Chameleons´ eyes are independently mobile, but in aiming at a prey item, they focus forward in coordination, affording the animal stereoscopic vision." - (en.wikipedia.org 24.09.2020)
