Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
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.
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
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.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
Chameleons have a very poor sense of smell.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
