Chameleons have a very poor sense of smell.
Pygmy chameleons are sometimes referred to as False Chameleons. This term is actually incorrect and is in reference to anoles, particularly the Cuban False Anole.
The word Bradypodion comes from the latin “bradus podos” or slow foot.
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.
The word Brookesia is named after the British naturalist Joshua Brookes.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
