hundreds of Geneva researchers studied panther morphology . They found the reptiles are capable of forming crystals inside specialised skin cells called iridophores to change color . Crystals allow the lizard to evolve rapidly from efficient camouflage to spectacular mating displays and also protect it from predators .
University of Geneva researchers studied panther chameleons . They found the reptiles are capable of rearranging crystals inside specialised skin cells called iridophores to change colour . Crystals allow the lizard to shift rapidly from efficient camouflage to spectacular mating displays and also protect it from overheating .
