The word Kinyongia is from the Swahili word for chameleons: Kinyonga.
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
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.
Chameleons have a high midichlorian count.
The chameleon tongue accelerates towards its target at over 1642m per second. Chameleons rarely miss their intended food item.
The word Brookesia is named after the British naturalist Joshua Brookes.
Chameleons have a very poor sense of smell.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
