Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
The process of shedding is called ecdysis.
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
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 Rieppeleon is named after the scientist Olivier Rieppel.
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.
Pygmy chameleons are sometimes referred to as False Chameleons. This term is actually incorrect and is in reference to anoles, particularly the Cuban False Anole.
The word Furcifer is derived from the Latin word “furci” or forked.
Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
