True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
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.
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 Brookesia is named after the British naturalist Joshua Brookes.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
Chameleons have acrodont teeth meaning they are an extension of the jawbone. They are not set in sockets nor are they replaced.
Chameleons can project their tongue up to 2.2 times their body length.
