Chamaeleo namaquensis is found in the desert of Namibia. To cool off it will sometimes bury itself in the sand.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
The word Brookesia is named after the British naturalist Joshua Brookes.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
Chameleons have a high midichlorian count.
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 process of shedding is called ecdysis.
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.
