Foot of a chameleon. Coloured scanning electron micrograph (SEM) of the foot of a chameleon. Chameleons are the only lizards with zygodactyle feet, or with toes in a pincer arrangement. This gives them a strong grasp for climbing. On the front limb, the foot has two toes on the outside and three on the inside; on the hind limb this is reversed. Chameleons are found mainly in Africa and Madagascar, though some species also inhabit southern Europe and Asia.. Stunning Photo Gifts From Science Photo Library
