Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
The chameleon tongue accelerates towards its target at over 1642m per second. Chameleons rarely miss their intended food item.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
Furcifer labordi (Labord’s Chameleon) has the shortest lifespan of only 4-5 months. It also has the shortest lifespan of any tetrapod!
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.
Chameleons have a very poor sense of smell.
True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
Chameleons have a high midichlorian count.
Some chameleons play dead to avoid predation; this is called thanatosis.
Trioceros schubotzi can be found at elevations as high as 4500m.
