The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
The word Brookesia is named after the British naturalist Joshua Brookes.
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.
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
Chameleons have acrodont teeth meaning they are an extension of the jawbone. They are not set in sockets nor are they replaced.
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.
Chameleons can project their tongue up to 2.2 times their body length.
Trioceros schubotzi can be found at elevations as high as 4500m.
