Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
The word Brookesia is named after the British naturalist Joshua Brookes.
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.
Trioceros schubotzi can be found at elevations as high as 4500m.
True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
The word Calumma comes from the Latin word for covering. This genus consists of chameleons from Madagascar with occipital lobes.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
Some chameleons play dead to avoid predation; this is called thanatosis.
