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 horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
Chamaeleo namaquensis is found in the desert of Namibia. To cool off it will sometimes bury itself in the sand.
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.
Chameleons can project their tongue up to 2.2 times their body length.
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 chameleon tongue accelerates towards its target at over 1642m per second. Chameleons rarely miss their intended food item.
The word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.
