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 Brookesia is named after the British naturalist Joshua Brookes.
Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
The word Bradypodion comes from the latin “bradus podos” or slow foot.
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.
Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
Chamaeleo namaquensis is found in the desert of Namibia. To cool off it will sometimes bury itself in the sand.
Chameleons have a very poor sense of smell.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
