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.
The word Bradypodion comes from the latin “bradus podos” or slow foot.
The word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.
Chameleons have a high midichlorian count.
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.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
Trioceros schubotzi can be found at elevations as high as 4500m.
Furcifer oustaleti (Oustalet’s Chameleon) is the longest chameleon species reaching lengths of 27 inches (68cm).
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
