Chameleons have a very poor sense of smell.
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
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.
Chamaeleo namaquensis is found in the desert of Namibia. To cool off it will sometimes bury itself in the sand.
The process of shedding is called ecdysis.
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
Chameleons can project their tongue up to 2.2 times their body length.
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
Some chameleons play dead to avoid predation; this is called thanatosis.
