The word Calumma comes from the Latin word for covering. This genus consists of chameleons from Madagascar with occipital lobes.
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
Chameleons have a very poor sense of smell.
The word Brookesia is named after the British naturalist Joshua Brookes.
Chameleons have acrodont teeth meaning they are an extension of the jawbone. They are not set in sockets nor are they replaced.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
