Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
The word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.
The word Brookesia is named after the British naturalist Joshua Brookes.
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.
Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
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.
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.
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.
