Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
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.
Some chameleons play dead to avoid predation; this is called thanatosis.
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
The word Bradypodion comes from the latin “bradus podos” or slow foot.
Chameleons have a high midichlorian count.
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.
True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
Trioceros schubotzi can be found at elevations as high as 4500m.
The word Kinyongia is from the Swahili word for chameleons: Kinyonga.
