The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
The word Rieppeleon is named after the scientist Olivier Rieppel.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
The word Brookesia is named after the British naturalist Joshua Brookes.
The word Kinyongia is from the Swahili word for chameleons: Kinyonga.
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 are sometimes referred to as False Chameleons. This term is actually incorrect and is in reference to anoles, particularly the Cuban False Anole.
The word Furcifer is derived from the Latin word “furci” or forked.
Chameleons have a high midichlorian count.
