The word Calumma comes from the Latin word for covering. This genus consists of chameleons from Madagascar with occipital lobes.
The process of shedding is called ecdysis.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
The chameleon tongue accelerates towards its target at over 1642m per second. Chameleons rarely miss their intended food item.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
Pygmy chameleons are sometimes referred to as False Chameleons. This term is actually incorrect and is in reference to anoles, particularly the Cuban False Anole.
Some chameleons play dead to avoid predation; this is called thanatosis.
Chameleons have laterally compressed bodies. This enables them to warm up quickly by presenting a larger surface area to the sun. It also helps some chameleon species blend in among the similarly shaped leaves in their environment.
The word Kinyongia is from the Swahili word for chameleons: Kinyonga.
