Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
The word Rieppeleon is named after the scientist Olivier Rieppel.
The process of shedding is called ecdysis.
The word Furcifer is derived from the Latin word “furci” or forked.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
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.
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 horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
Chameleons have a high midichlorian count.
