Chameleons are a group of lizards that are known for their ability to change color, and are native to various regions around the world. They are found primarily in Africa and Madagascar, but also in parts of Asia, Europe, and the Americas.The majority of chameleon species are found in Africa, with over half of all known species being native to the island of Madagascar. African chameleons can be found in a wide variety of habitats, including forests, savannas, and deserts. Madagascar is home to many unique species of chameleons, many of which are found nowhere else in the world. These species are often brightly colored, and are known for their large eyes and long tongues.Chameleons are also found in Asia, specifically in India, Sri Lanka, and Southeast Asia. These species are typically smaller and less colorful than their African and Madagascan counterparts.

These species are small and have very limited ranges. In the Americas, chameleons are found only in the Caribbean, specifically in the Bahamas and Cuba. These species are also small and have limited ranges.Chameleons are known for their unique ability to change color, which allows them to camouflage themselves in their surroundings and to communicate with other chameleons. This ability is due to specialized cells called chromatophores that contain pigments. The color change is controlled by hormones and is used for different reasons such as communication, thermoregulation or camouflage.In conclusion, Chameleons are a group of lizards that are known for their ability to change color, and are native to various regions around the world.
