Chameleons can project their tongue up to 2.2 times their body length.
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 do not have external ears or a tympanic membrane, but they do have internal ears as well as degenerated middle ears. They do not hear well but they can detect low frequency sounds.
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.
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
The word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.
Trioceros schubotzi can be found at elevations as high as 4500m.
The process of shedding is called ecdysis.
