Some chameleons play dead to avoid predation; this is called thanatosis.
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 word Chamaeleo is derived via Latin from the Greek word khamaileon. It roughly translates to ground lion. Khamai means on the ground and leon means lion.
Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
Chameleons have acrodont teeth meaning they are an extension of the jawbone. They are not set in sockets nor are they replaced.
The word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.
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.
