Some species have highly developed colour-changing abilities, caused by stress and changes in the intensity of light and temperature, which alter the dispersal of pigment granules in the layers of cells beneath the outer skin. The tail is long and highly prehensile, assisting the animal when climbing.
Most chameleons live in trees and move very slowly.
The eyes are on 'turrets', move independently, and can swivel forward to give stereoscopic vision for 'shooting'.
