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.
Some chameleons play dead to avoid predation; this is called thanatosis.
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 have a high midichlorian count.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
The word Kinyongia is from the Swahili word for chameleons: Kinyonga.
Trioceros schubotzi can be found at elevations as high as 4500m.
True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
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.
