Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
The word Furcifer is derived from the Latin word “furci” or forked.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
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.
Pygmy chameleons are sometimes referred to as False Chameleons. This term is actually incorrect and is in reference to anoles, particularly the Cuban False Anole.
Some chameleons play dead to avoid predation; this is called thanatosis.
The oldest known chameleon fossil is from the extinct species Chamaeleo caroliquarti. It was found in Europe and is 26 million years old.
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!
