Chameleons have a very poor sense of smell.
The word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.
Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
Chameleons have acrodont teeth meaning they are an extension of the jawbone. They are not set in sockets nor are they replaced.
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.
Furcifer labordi (Labord’s Chameleon) has the shortest lifespan of only 4-5 months. It also has the shortest lifespan of any tetrapod!
The word Brookesia is named after the British naturalist Joshua Brookes.
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.
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.
