Pygmy chameleons are sometimes referred to as False Chameleons. This term is actually incorrect and is in reference to anoles, particularly the Cuban False Anole.
The word Chamaeleo is derived via Latin from the Greek word khamaileon. It roughly translates to ground lion. Khamai means on the ground and leon means lion.
The word Bradypodion comes from the latin “bradus podos” or slow foot.
The word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.
The oldest known chameleon fossil is from the extinct species Chamaeleo caroliquarti. It was found in Europe and is 26 million years old.
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.
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
The word Kinyongia is from the Swahili word for chameleons: Kinyonga.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
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.
