The animal known for its ability to change color is the chameleon. These fascinating reptiles can alter their skin color as a means of communication, camouflage, or temperature regulation. Chameleons have specialized cells known as chromatophores, which contain different pigments and can expand or contract to display various hues. While many people associate color change with mood or environmental adaptation, it is often more about social signaling, helping chameleons blend in with their surroundings to evade predators or convey dominance during mating displays.
