Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
The oldest known chameleon fossil is from the extinct species Chamaeleo caroliquarti. It was found in Europe and is 26 million years old.
Chameleons can project their tongue up to 2.2 times their body length.
The word Bradypodion comes from the latin “bradus podos” or slow foot.
The word Furcifer is derived from the Latin word “furci” or forked.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
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 Kinyongia is from the Swahili word for chameleons: Kinyonga.
Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
Chameleons have a high midichlorian count.
