The process of shedding is called ecdysis.
Chameleons have a very poor sense of smell.
The word Rieppeleon is named after the scientist Olivier Rieppel.
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
Chameleons have laterally compressed bodies. This enables them to warm up quickly by presenting a larger surface area to the sun. It also helps some chameleon species blend in among the similarly shaped leaves in their environment.
True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
The oldest known chameleon fossil is from the extinct species Chamaeleo caroliquarti. It was found in Europe and is 26 million years old.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
