Chameleon

If you've ever had the opportunity to watch a chameleon in action, you know that they can move their eyes independently – while one eye looks backwards, the other can be looking straight ahead, or to the side. This allows chameleons to check out their surroundings when searching for food, without having to move to move their head. Once a tasty bug is spotted, both eyes focus on the food and a chameleon is able to use depth perception to judge the distance.
