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 word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.
Chameleons have a very poor sense of smell.
Furcifer labordi (Labord’s Chameleon) has the shortest lifespan of only 4-5 months. It also has the shortest lifespan of any tetrapod!
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
The word Chamaeleo is derived via Latin from the Greek word khamaileon. It roughly translates to ground lion. Khamai means on the ground and leon means lion.
The word Furcifer is derived from the Latin word “furci” or forked.
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
