Chameleon is a small lizard with a length not more than 25-30 centimeters.
The chameleon is one amazing ability to change color from bright green to gray-black, or yellow. It is believed that he was doing it to disguise the colour of the environment. There is even a completely unfounded opinion that the chameleon is able not only to change the color of the body, but also to reproduce any image of the surrounding background, until the black and white squares of a chessboard. However, this is not the case.
The fact that the chameleon has a very transparent skin, under which cells are red, black and yellow. When the chameleon is angry or in fear, his nervous system sends signals to these cells, they contract and expand, which gives the impression that the skin changes its color. Being in a calm state, lizard painted in a reddish-brown color, sometimes with faint transverse stripes.
If the chameleon angry, his skin becomes dark, when excited or frightened, it becomes pale yellow hues. In the heat of the cells under the skin have a black tint. But in the dark skin of a chameleon cream with yellow spots.
