Some chameleons play dead to avoid predation; this is called thanatosis.
Chameleons have a high midichlorian count.
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.
Chameleons have a very poor sense of smell.
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.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
