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.
Chameleons can project their tongue up to 2.2 times their body length.
Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
The word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.

The word Furcifer is derived from the Latin word “furci” or forked.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
The word Bradypodion comes from the latin “bradus podos” or slow foot.
