Chameleons have laterally flattened bodies and bulging, independently rotating eyes. They are variously ornamented with crests, horns, and spines. They feed chiefly on insects and are unique among lizards in possessing long, sticky tongues with which they capture their prey. Their changes in skin color are under hormonal and nervous control and are not affected by the color of the background but by stimuli such as light, temperature, and emotion. “Chameleon” is derived from what Greek words?
