Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
The chameleon tongue accelerates towards its target at over 1642m per second. Chameleons rarely miss their intended food item.
Furcifer oustaleti (Oustalet’s Chameleon) is the longest chameleon species reaching lengths of 27 inches (68cm).
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
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.
The process of shedding is called ecdysis.
Chameleons can project their tongue up to 2.2 times their body length.
True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
