Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
Chameleons have acrodont teeth meaning they are an extension of the jawbone. They are not set in sockets nor are they replaced.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
The process of shedding is called ecdysis.
The word Rieppeleon is named after the scientist Olivier Rieppel.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
The smallest chameleon species is Brookesia micra with an adult length just over 1 inch (29mm). It hatches from an egg no bigger than a grain of rice!
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.
Some chameleons play dead to avoid predation; this is called thanatosis.
