Trioceros schubotzi can be found at elevations as high as 4500m.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
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.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
The word Rieppeleon is named after the scientist Olivier Rieppel.
Chameleons do not have external ears or a tympanic membrane, but they do have internal ears as well as degenerated middle ears. They do not hear well but they can detect low frequency sounds.
Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
The word Brookesia is named after the British naturalist Joshua Brookes.
