There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
Some chameleons play dead to avoid predation; this is called thanatosis.
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 largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
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!
Chameleons have a very poor sense of smell.
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
The oldest known chameleon fossil is from the extinct species Chamaeleo caroliquarti. It was found in Europe and is 26 million years old.
