Chamaeleo namaquensis is found in the desert of Namibia. To cool off it will sometimes bury itself in the sand.
Trioceros schubotzi can be found at elevations as high as 4500m.
Some chameleons play dead to avoid predation; this is called thanatosis.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
Chameleons change color by rearranging a lattice of nanocrystals in one of their top layers of skin cells called iridophores. Chameleons can then stretch this layer, broadening the nanocrystalline lattice, thereby causing it to reflect a different wavelength of light.
The word Furcifer is derived from the Latin word “furci” or forked.
The word Calumma comes from the Latin word for covering. This genus consists of chameleons from Madagascar with occipital lobes.
