Biology of the Chameleon The Old World chameleon is a pinnacle of evolution. They have evolved numerous biological and anatomical adaptations that make them supreme hunters and masters of camouflage. The most interesting adaptations that chameleons possess are their eyes, tongue, feet, tail, skin attributes, and their often unusual physical adornments. Eyes - The eyes of a chameleon are one of the most important features a chameleon has in order to hunt. Their independently rotating eyes allow them to look in two directions at once. This enables them to search for prey over a larger area, as well as the ability to watch out for predators while doing this. Once a chameleon has spotted a food item, it looks at it with both eyes so it can accurately judge distance. Chameleon's have excellent eyesight, able to achieve accuracy of close to 100%. Every once in awhile, a wild caught chameleon will come in missing one eye. Although this is a disadvantage, the chameleon is still able to hunt for food, but with a lower success rate. A chameleon must clean its eyes in order to ward off infections and keep their eyesight good.
