The word Calumma comes from the Latin word for covering. This genus consists of chameleons from Madagascar with occipital lobes.
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 smallest chameleon species is Brookesia micra with an adult length just over 1 inch (29mm). It hatches from an egg no bigger than a grain of rice!
Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
Chameleons have acrodont teeth meaning they are an extension of the jawbone. They are not set in sockets nor are they replaced.
The word Furcifer is derived from the Latin word “furci” or forked.
