True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
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!
The process of shedding is called ecdysis.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
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.
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
Chameleons have a very poor sense of smell.
Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
