This reptilian superhero can alter the pigments in its skin cells to change color, operate its eyes separately (allowing it to keep one eye on dinner and one out for predators), capture that dinner by lashing out its long, super-fast, sticky tongue at speeds up to 13 miles an hour, and use its prehensile tail as an anchor. Ranging in size from less than an inch (Nano-chameleon, possibly the world's smallest reptile) to about two feet long, the size of a house cat (Parson's Chameleon), the chameleon is something to behold!
