Chameleons

Chameleons are mostly found in in Africa's, southern Sahara desert. There are around various types of this species in the world. The common chameleon ranges from the Middle East, along the northern African coast to southern Spain.

    This slow-moving lizard hunts insects, its prey. They eat insects among trees and undergrowth. One of its special features is its eyes. Both of its eyes are set in two conical sockets. They can move independently of one another. This enables chameleons to see in front with one eye and behind with the other.

    Chameleons are popular due to their ability to change their colour. A chameleon can change and match its skin colour with the surroundings in order to disguise itself and is difficult to spot among foliage. This is why we say a chameleon 'camouflages ' itself.

    When there is a fine insect flying around it, it shoots out a long, sticky tongue to its target and draws the insect back into its mouth.
