Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
The word Bradypodion comes from the latin “bradus podos” or slow foot.
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
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 word Rieppeleon is named after the scientist Olivier Rieppel.
The word Furcifer is derived from the Latin word “furci” or forked.
The word Chamaeleo is derived via Latin from the Greek word khamaileon. It roughly translates to ground lion. Khamai means on the ground and leon means lion.
Furcifer labordi (Labord’s Chameleon) has the shortest lifespan of only 4-5 months. It also has the shortest lifespan of any tetrapod!
