The term "χameleon" refers to a type of lizard known for its ability to change color. These reptiles belong to the family Chamaeleonidae and are primarily found in Africa and Madagascar, although some species inhabit parts of Asia and Europe. Chameleons use color change for communication, temperature regulation, and camouflage. Chameleons have unique physical features, including a long, sticky tongue that can extend rapidly to catch prey. They also possess independently moving eyes, allowing them to see in different directions simultaneously. Their distinctive appearance and behaviors make them popular in both the wild and as exotic pets.
