True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
The word Kinyongia is from the Swahili word for chameleons: Kinyonga.
Chameleons have a high midichlorian count.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
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.
The word Rieppeleon is named after the scientist Olivier Rieppel.
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
