Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
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.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
The process of shedding is called ecdysis.
Chameleons have a very poor sense of smell.
The word Kinyongia is from the Swahili word for chameleons: Kinyonga.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
