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!
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
Pygmy chameleons are sometimes referred to as False Chameleons. This term is actually incorrect and is in reference to anoles, particularly the Cuban False Anole.
The word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.
The oldest known chameleon fossil is from the extinct species Chamaeleo caroliquarti. It was found in Europe and is 26 million years old.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
