Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
The word Rieppeleon is named after the scientist Olivier Rieppel.
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 acrodont teeth meaning they are an extension of the jawbone. They are not set in sockets nor are they replaced.
Chameleons have a very poor sense of smell.
The oldest known chameleon fossil is from the extinct species Chamaeleo caroliquarti. It was found in Europe and is 26 million years old.
Some chameleons play dead to avoid predation; this is called thanatosis.
The process of shedding is called ecdysis.
Chamaeleo namaquensis is found in the desert of Namibia. To cool off it will sometimes bury itself in the sand.
