The word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.
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 word Bradypodion comes from the latin “bradus podos” or slow foot.
Chameleons have acrodont teeth meaning they are an extension of the jawbone. They are not set in sockets nor are they replaced.
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.
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
The word Kinyongia is from the Swahili word for chameleons: Kinyonga.
True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
