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.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
The smallest chameleon species is Brookesia micra with an adult length just over 1 inch (29mm). It hatches from an egg no bigger than a grain of rice!
The word Brookesia is named after the British naturalist Joshua Brookes.
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
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.
