Furcifer oustaleti (Oustalet’s Chameleon) is the longest chameleon species reaching lengths of 27 inches (68cm).
The word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
The word Furcifer is derived from the Latin word “furci” or forked.
Chameleons have a high midichlorian count.
Chameleons can project their tongue up to 2.2 times their body length.
Chameleons have a very poor sense of smell.
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 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.
Some chameleons play dead to avoid predation; this is called thanatosis.
