Furcifer oustaleti (Oustalet’s Chameleon) is the longest chameleon species reaching lengths of 27 inches (68cm).
The word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.
The process of shedding is called ecdysis.
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.
The chameleon tongue accelerates towards its target at over 1642m per second. Chameleons rarely miss their intended food item.
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
Chameleons have a very poor sense of smell.
Chameleons can project their tongue up to 2.2 times their body length.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
