Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
Some chameleons play dead to avoid predation; this is called thanatosis.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
The chameleon tongue accelerates towards its target at over 1642m per second. Chameleons rarely miss their intended food item.
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
Chameleons can project their tongue up to 2.2 times their body length.
True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
Trioceros schubotzi can be found at elevations as high as 4500m.
Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
