How do Chameleon's Change Color? Chameleons exhibit remarkable optical phenomena. A chameleonâs skin can quickly and dramatically change color, its eyes allow it to look in almost all directions without moving its head, and it even has a rudimentary third eye! More than 100 species of true chameleons exist. They are found in Africa, Madagascar, Spain, southern Europe, Arabia, India, Sri Lanka, and the Seychelles Islands. Several color-changing lizards in the United States, commonly called anoles, are also popularly called chameleons.
The most obvious reason such a soft-bodied animal would change color is to hide from predatorsâand octopuses are very good at this. They can change not only their coloring, but also the texture of their skin to match rocks, corals and other items nearby.esides chromatophores, some cephalopods also have iridophores and leucophores. Iridophores have stacks of reflecting plates that create iridescent greens, blues, silvers and golds, while leucophores mirror back the colors of the environment, making the animal less conspicuous.
