The <b>chameleons (<b>Chamaeleonidae) are a family of small scaly sauropsids (reptiles). There are about 161 species of chameleons, most of them in Africa south of the Sahara.
In America, lizards of the family of anoles, which bear no special relationship to true chameleons, are often called chameleons. They are famous for their ability to change color depending on the circumstances, for their quick and elongated tongue, and for their eyes, which can move independently of each other.
The group is quite old, since chameleon fossils are known from the Paleocene. The family is related with the agámidos.
