Everybody knows that these creatures are able to change the color of their skin. They are able to vary the color from pink to turquoise. The question is – what for?

The change of the color is a kind of the reaction to various environmental conditions. They change the color when it is too hot/cold or when they "smell" danger. It is an interesting fact that males make their skin coloration lighter/brighter in order to court female species.
