Good questions. In this case of these guys it does not seem to correspond to temp, humidity, stress or background colorations. It seems random.What confuses the bejeezus out of me is the how. Where and what are the photoreceptors that respond to the environment? What decided to undertake altering then skin color? What mechanisms are involved that not only alters the color but correctly selects the new color?
