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.
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
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.
The process of shedding is called ecdysis.
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.
The chameleon tongue accelerates towards its target at over 1642m per second. Chameleons rarely miss their intended food item.
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
