Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
Furcifer oustaleti (Oustalet’s Chameleon) is the longest chameleon species reaching lengths of 27 inches (68cm).
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.
The word Kinyongia is from the Swahili word for chameleons: Kinyonga.
The chameleon tongue accelerates towards its target at over 1642m per second. Chameleons rarely miss their intended food item.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
The oldest known chameleon fossil is from the extinct species Chamaeleo caroliquarti. It was found in Europe and is 26 million years old.
Trioceros schubotzi can be found at elevations as high as 4500m.
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.
