Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
Chameleons can project their tongue up to 2.2 times their body length.
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 largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
Trioceros schubotzi can be found at elevations as high as 4500m.
Furcifer oustaleti (Oustalet’s Chameleon) is the longest chameleon species reaching lengths of 27 inches (68cm).
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
Chamaeleo namaquensis is found in the desert of Namibia. To cool off it will sometimes bury itself in the sand.
