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.
Some chameleons play dead to avoid predation; this is called thanatosis.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
