The animal famous for its ability to change color is the chameleon. Chameleons possess specialized cells called chromatophores that contain different pigments. By expanding or contracting these cells, chameleons can alter their skin color for various purposes, including camouflage, communication, and temperature regulation. It's fascinating how they can blend into their surroundings or display vibrant hues to express emotions or attract mates. Their ability to change color has made them popular subjects in research and media, highlighting their unique adaptations to their environments.
