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 have acrodont teeth meaning they are an extension of the jawbone. They are not set in sockets nor are they replaced.
The word Rieppeleon is named after the scientist Olivier Rieppel.
Trioceros schubotzi can be found at elevations as high as 4500m.
The process of shedding is called ecdysis.
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
Furcifer labordi (Labord’s Chameleon) has the shortest lifespan of only 4-5 months. It also has the shortest lifespan of any tetrapod!
The word Furcifer is derived from the Latin word “furci” or forked.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
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.
