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 Furcifer is derived from the Latin word “furci” or forked.

The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
The word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
