Chameleons (Chamaeleonidae) are a family of unique lizards with unusual characteristics: rapidly extendable tongues, feet with two toes pointing forward and two backward, a prehensile tail, and eyes that can move independently of each other. Many species also have the ability to change the color of their skin.
