The oldest known chameleon fossil is from the extinct species Chamaeleo caroliquarti. It was found in Europe and is 26 million years old.
Chameleons can project their tongue up to 2.2 times their body length.
Chameleons have a high midichlorian count.
Chamaeleo namaquensis is found in the desert of Namibia. To cool off it will sometimes bury itself in the sand.
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
Trioceros schubotzi can be found at elevations as high as 4500m.
The word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.
Some chameleons play dead to avoid predation; this is called thanatosis.
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
