Chameleons have a very poor sense of smell.
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.
The word Furcifer is derived from the Latin word “furci” or forked.
Some chameleons play dead to avoid predation; this is called thanatosis.
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.
