True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
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.
The word Calumma comes from the Latin word for covering. This genus consists of chameleons from Madagascar with occipital lobes.
Furcifer oustaleti (Oustalet’s Chameleon) is the longest chameleon species reaching lengths of 27 inches (68cm).
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
Chameleons have a very poor sense of smell.
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.
