Why do chameleons change their body Colour?
Since chameleons can’t generate their own body heat, changing the color of their skin is a way to maintain a favorable body temperature. A cold chameleon may become dark to absorb more heat, whereas a hotter chameleon may turn pale to reflect the sun’s heat. Chameleons will also use bold color changes to communicate.
How does a chameleon change its skin Colour?
