Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
Chameleons have a very poor sense of smell.
True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
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.
Pygmy chameleons are sometimes referred to as False Chameleons. This term is actually incorrect and is in reference to anoles, particularly the Cuban False Anole.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
Furcifer oustaleti (Oustalet’s Chameleon) is the longest chameleon species reaching lengths of 27 inches (68cm).
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.
