Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
The word Furcifer is derived from the Latin word “furci” or forked.
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.
The smallest chameleon species is Brookesia micra with an adult length just over 1 inch (29mm). It hatches from an egg no bigger than a grain of rice!
True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
Chameleons do not have external ears or a tympanic membrane, but they do have internal ears as well as degenerated middle ears. They do not hear well but they can detect low frequency sounds.
Furcifer labordi (Labord’s Chameleon) has the shortest lifespan of only 4-5 months. It also has the shortest lifespan of any tetrapod!
Trioceros schubotzi can be found at elevations as high as 4500m.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
The word Rieppeleon is named after the scientist Olivier Rieppel.
