Chameleons can project their tongue up to 2.2 times their body length.
The process of shedding is called ecdysis.
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 word Calumma comes from the Latin word for covering. This genus consists of chameleons from Madagascar with occipital lobes.
Chameleons have a very poor sense of smell.
The word Rieppeleon is named after the scientist Olivier Rieppel.
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
Trioceros schubotzi can be found at elevations as high as 4500m.
Chamaeleo namaquensis is found in the desert of Namibia. To cool off it will sometimes bury itself in the sand.
