Chameleons have a very poor sense of smell.
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
The word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling 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.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
The process of shedding is called ecdysis.
The word Calumma comes from the Latin word for covering. This genus consists of chameleons from Madagascar with occipital lobes.
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
