Chameleon changing coloration – Depending on the temperature, the ambient atmosphere and change color chameleon skin. Scientists have recently discovered the mechanism of this phenomenon: in the skin of lizards are cells called iridophores, which contain small crystals, reflecting light. Chameleon can tune these crystals, changing the distance between them. In this way, a spectrum of colors, which determines the number of nanocrystals and their distance to each other.
