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.
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.
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.
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.
Some chameleons play dead to avoid predation; this is called thanatosis.
Chameleons have a high midichlorian count.
The chameleon tongue accelerates towards its target at over 1642m per second. Chameleons rarely miss their intended food item.
The word Kinyongia is from the Swahili word for chameleons: Kinyonga.
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
