Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
Trioceros schubotzi can be found at elevations as high as 4500m.
The word Furcifer is derived from the Latin word “furci” or forked.
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.
True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
The oldest known chameleon fossil is from the extinct species Chamaeleo caroliquarti. It was found in Europe and is 26 million years old.
Chamaeleo namaquensis is found in the desert of Namibia. To cool off it will sometimes bury itself in the sand.
The word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.
Chameleons have a very poor sense of smell.
