Chameleons can project their tongue up to 2.2 times their body length.
Furcifer oustaleti (Oustalet’s Chameleon) is the longest chameleon species reaching lengths of 27 inches (68cm).
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
The word Rieppeleon is named after the scientist Olivier Rieppel.
The chameleon tongue accelerates towards its target at over 1642m per second. Chameleons rarely miss their intended food item.
The word Bradypodion comes from the latin “bradus podos” or slow foot.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
Some chameleons play dead to avoid predation; this is called thanatosis.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
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.
