Chameleons can project their tongue up to 2.2 times their body length.
Furcifer labordi (Labord’s Chameleon) has the shortest lifespan of only 4-5 months. It also has the shortest lifespan of any tetrapod!
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
Chamaeleo namaquensis is found in the desert of Namibia. To cool off it will sometimes bury itself in the sand.
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
The word Kinyongia is from the Swahili word for chameleons: Kinyonga.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
Chameleons have acrodont teeth meaning they are an extension of the jawbone. They are not set in sockets nor are they replaced.
Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
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.
