Chameleons have a high midichlorian count.
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.
Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
The word Calumma comes from the Latin word for covering. This genus consists of chameleons from Madagascar with occipital lobes.
The word Rieppeleon is named after the scientist Olivier Rieppel.
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 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!
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
Chameleons have a very poor sense of smell.
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
