The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
The word Furcifer is derived from the Latin word “furci” or forked.
True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
The word Brookesia is named after the British naturalist Joshua Brookes.
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
The word Calumma comes from the Latin word for covering. This genus consists of chameleons from Madagascar with occipital lobes.
The word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.
The word Kinyongia is from the Swahili word for chameleons: Kinyonga.
The chameleon tongue accelerates towards its target at over 1642m per second. Chameleons rarely miss their intended food item.
