The animal known for its ability to change colors for camouflage is the chameleon. Chameleons belong to the family Chamaeleonidae and are famous for their unique color-changing abilities. They can alter their skin color for various reasons, including communication, temperature regulation, and camouflage to avoid predators. While many people believe chameleons change color solely for disguise or blending into their surroundings, they also use colors to express mood or social signals. This fascinating ability is due to special pigment cells in their skin, known as chromatophores.
