Some chameleons play dead to avoid predation; this is called thanatosis.
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
The chameleon tongue accelerates towards its target at over 1642m per second. Chameleons rarely miss their intended food item.
The process of shedding is called ecdysis.
Chameleons have acrodont teeth meaning they are an extension of the jawbone. They are not set in sockets nor are they replaced.
Chameleons do not have external ears or a tympanic membrane, but they do have internal ears as well as degenerated middle ears. They do not hear well but they can detect low frequency sounds.
Chameleons can project their tongue up to 2.2 times their body length.
The word Furcifer is derived from the Latin word “furci” or forked.
Chamaeleo namaquensis is found in the desert of Namibia. To cool off it will sometimes bury itself in the sand.
