Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
The word Calumma comes from the Latin word for covering. This genus consists of chameleons from Madagascar with occipital lobes.
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
The word Bradypodion comes from the latin “bradus podos” or slow foot.
Chameleons can project their tongue up to 2.2 times their body length.
Chamaeleo namaquensis is found in the desert of Namibia. To cool off it will sometimes bury itself in the sand.
Chameleons have laterally compressed bodies. This enables them to warm up quickly by presenting a larger surface area to the sun. It also helps some chameleon species blend in among the similarly shaped leaves in their environment.
Trioceros schubotzi can be found at elevations as high as 4500m.
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 have bicuspid claws where each claw has two points like a crescent moon.
