The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
The word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
The oldest known chameleon fossil is from the extinct species Chamaeleo caroliquarti. It was found in Europe and is 26 million years old.
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
Chameleons have a very poor sense of smell.
