Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
Chameleons have a very poor sense of smell.
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
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.
Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
Furcifer oustaleti (Oustalet’s Chameleon) is the longest chameleon species reaching lengths of 27 inches (68cm).
The word Kinyongia is from the Swahili word for chameleons: Kinyonga.
The word Calumma comes from the Latin word for covering. This genus consists of chameleons from Madagascar with occipital lobes.
Chameleons can project their tongue up to 2.2 times their body length.
