SECRET OF CHAMELEONS' COLOR CHANGE

It    is   the light reflecting cells in   the skin that   provide chameleon   their uncanny   color-changing   abilities that help them attract mates   and ward off predators .Unlike other animals   that change color , such as the squid   and Octopus ,   Chameleon do    not   modify their hues   by accumulating   or   dispersing    pigments   within their   skin cells.
Instead    the lizards     rely on    structural changes    that affect how light reflects off their skin Researchers found that chameleons    have two super posed thick layers of iridophores cells ,that have pigment and reflect light
The    iridophores   cells   contain   nano crystals of different sizes , shape and organizations, key to the Chameleons'   dramatic color shifts, according to    researchers.The Chameleon change the structural arrangement of the cells by relaxing or exiting the skin, which leads to a change in color.
