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.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
Trioceros schubotzi can be found at elevations as high as 4500m.
Furcifer oustaleti (Oustalet’s Chameleon) is the longest chameleon species reaching lengths of 27 inches (68cm).
The word Calumma comes from the Latin word for covering. This genus consists of chameleons from Madagascar with occipital lobes.
Chameleons have a high midichlorian count.
