Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
Trioceros schubotzi can be found at elevations as high as 4500m.
The word Bradypodion comes from the latin “bradus podos” or slow foot.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
The oldest known chameleon fossil is from the extinct species Chamaeleo caroliquarti. It was found in Europe and is 26 million years old.
Chameleons have a very poor sense of smell.
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.
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.
