Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
The process of shedding is called ecdysis.
The chameleon tongue accelerates towards its target at over 1642m per second. Chameleons rarely miss their intended food item.
The word Calumma comes from the Latin word for covering. This genus consists of chameleons from Madagascar with occipital lobes.
True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
Some chameleons play dead to avoid predation; this is called thanatosis.
The word Kinyongia is from the Swahili word for chameleons: Kinyonga.
The word Rieppeleon is named after the scientist Olivier Rieppel.
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
