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.
Chameleons can project their tongue up to 2.2 times their body length.
The word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.
Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
Furcifer oustaleti (Oustalet’s Chameleon) is the longest chameleon species reaching lengths of 27 inches (68cm).
The word Brookesia is named after the British naturalist Joshua Brookes.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
Chameleons have a high midichlorian count.
Trioceros schubotzi can be found at elevations as high as 4500m.
