Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
The word Furcifer is derived from the Latin word “furci” or forked.
The word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
The word Chamaeleo is derived via Latin from the Greek word khamaileon. It roughly translates to ground lion. Khamai means on the ground and leon means lion.
Chameleons change color by rearranging a lattice of nanocrystals in one of their top layers of skin cells called iridophores. Chameleons can then stretch this layer, broadening the nanocrystalline lattice, thereby causing it to reflect a different wavelength of light.
Chameleons have a high midichlorian count.
