Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
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.
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.
Some chameleons play dead to avoid predation; this is called thanatosis.
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
The word Brookesia is named after the British naturalist Joshua Brookes.
Trioceros schubotzi can be found at elevations as high as 4500m.
The word Chamaeleo is derived via Latin from the Greek word khamaileon. It roughly translates to ground lion. Khamai means on the ground and leon means lion.
Pygmy chameleons are sometimes referred to as False Chameleons. This term is actually incorrect and is in reference to anoles, particularly the Cuban False Anole.
