The word Calumma comes from the Latin word for covering. This genus consists of chameleons from Madagascar with occipital lobes.
The chameleon tongue accelerates towards its target at over 1642m per second. Chameleons rarely miss their intended food item.
Furcifer oustaleti (Oustalet’s Chameleon) is the longest chameleon species reaching lengths of 27 inches (68cm).
Chamaeleo namaquensis is found in the desert of Namibia. To cool off it will sometimes bury itself in the sand.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
Chameleons do not have external ears or a tympanic membrane, but they do have internal ears as well as degenerated middle ears. They do not hear well but they can detect low frequency sounds.
The process of shedding is called ecdysis.
The word Rieppeleon is named after the scientist Olivier Rieppel.
Chameleons have a very poor sense of smell.
