Chameleons’ Color Change Secret Revealed
Chameleons are known for the remarkable ability to perform complex and rapid color changes during social interactions. Now, a team of scientists from the University of Geneva (UNIGE), Switzerland, has unveiled exactly how chameleons change their colors. According to the research team’s findings, chameleons can adjust a system of nanocrystals in their skin cells, called iridophores. Better yet, chameleons have two layers of these iridophores, and the second layer reflects infrared light. These two layers can be controlled independently of each other, enabling chameleons to put on their colorful displays.…
