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 horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
Chameleons can project their tongue up to 2.2 times their body length.
The chameleon tongue accelerates towards its target at over 1642m per second. Chameleons rarely miss their intended food item.
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!
Chameleons have a very poor sense of smell.
The word Brookesia is named after the British naturalist Joshua Brookes.
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
