Not all lizards are able to change the color of their skin to blend in with their surroundings. Therefore Aegean wall lizards, for example, camouflage by choosing rocks that best match the color of their backs, thus ensuring they are able to remain hidden from avian predators.
Lizards use bright colors to attract mates but this also makes their camouflage less effective, making them visible to predators, report researchers from the University of Cambridge.
Camouflage has always been one of nature's greatest accomplishments in the eyes of man. It's a skill we can barely imitate despite how far technology has come. Now researchers are at least a step closer to understanding how chameleons do it, revealing a stunning and unexpected system just beneath their skin.
