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.
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.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
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 chameleon tongue accelerates towards its target at over 1642m per second. Chameleons rarely miss their intended food item.
Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
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.
The process of shedding is called ecdysis.
Furcifer labordi (Labord’s Chameleon) has the shortest lifespan of only 4-5 months. It also has the shortest lifespan of any tetrapod!
