Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
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.
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
The word Furcifer is derived from the Latin word “furci” or forked.
Chameleons can project their tongue up to 2.2 times their body length.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
The word Brookesia is named after the British naturalist Joshua Brookes.
The chameleons tongue accelerates towards its target at over 1642m per second. Chameleons rarely miss their intended food item.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
Chamaeleo namaquensis is found in the desert of Namibia. To cool off it will sometimes bury itself in the sand.
