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.
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
The word Furcifer is derived from the Latin word “furci” or forked.
The word Bradypodion comes from the latin “bradus podos” or slow foot.
The word Rieppeleon is named after the scientist Olivier Rieppel.
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.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
