This desert chameleon has heat-thermostat skin! [Biology]
posted January 31 2013 19:57.26 by Giorgos Lazaridis




Evolution gifted this chameleon with a unique feature to regulate is body temperature using its skin color as a thermostat. Being a cold-blooded animal, it needs to absorb as much energy from the morning sun as possible, so our friend gets a dark color to absorb the sun light more effectively. As the sun gets higher and hotter, the chameleon renders its color white to deflect rather o collect the light! Life is so amazing...
