True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
Furcifer oustaleti (Oustalet’s Chameleon) is the longest chameleon species reaching lengths of 27 inches (68cm).
The word Rieppeleon is named after the scientist Olivier Rieppel.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
The chameleon tongue accelerates towards its target at over 1642m per second. Chameleons rarely miss their intended food item.
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 oldest known chameleon fossil is from the extinct species Chamaeleo caroliquarti. It was found in Europe and is 26 million years old.
The process of shedding is called ecdysis.
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
