Chameleons have acrodont teeth meaning they are an extension of the jawbone. They are not set in sockets nor are they replaced.
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.
The word Kinyongia is from the Swahili word for chameleons: Kinyonga.
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
The word Chamaeleo is derived via Latin from the Greek word khamaileon. It roughly translates to ground lion. Khamai means on the ground and leon means lion.
Chameleons can project their tongue up to 2.2 times their body length.
The word Rieppeleon is named after the scientist Olivier Rieppel.
Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
Some chameleons play dead to avoid predation; this is called thanatosis.
