The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
Chameleons have a high midichlorian count.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
The process of shedding is called ecdysis.
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.
True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
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.
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 do have taste buds on their tongue but overall they have a poor sense of taste.
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
