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 Rieppeleon is named after the scientist Olivier Rieppel.
Chamaeleo namaquensis is found in the desert of Namibia. To cool off it will sometimes bury itself in the sand.
The process of shedding is called ecdysis.
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
The smallest chameleon species is Brookesia micra with an adult length just over 1 inch (29mm). It hatches from an egg no bigger than a grain of rice!
The word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.
The word Calumma comes from the Latin word for covering. This genus consists of chameleons from Madagascar with occipital lobes.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
