Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
The word Bradypodion comes from the latin “bradus podos” or slow foot.
The word Rieppeleon is named after the scientist Olivier Rieppel.
Furcifer oustaleti (Oustalet’s Chameleon) is the longest chameleon species reaching lengths of 27 inches (68cm).
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.
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.
Some chameleons play dead to avoid predation; this is called thanatosis.
Chameleons have a very poor sense of smell.
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
