Chameleons have acrodont teeth meaning they are an extension of the jawbone. They are not set in sockets nor are they replaced.
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.
The chameleon tongue accelerates towards its target at over 1642m per second. Chameleons rarely miss their intended food item.
The process of shedding is called ecdysis.
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 have bicuspid claws where each claw has two points like a crescent moon.
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 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.
