Chameleons have acrodont teeth meaning they are an extension of the jawbone. They are not set in sockets nor are they replaced.
The process of shedding is called ecdysis.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
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 high midichlorian count.
The oldest known chameleon fossil is from the extinct species Chamaeleo caroliquarti. It was found in Europe and is 26 million years old.
Trioceros schubotzi can be found at elevations as high as 4500m.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
Some chameleons play dead to avoid predation; this is called thanatosis.
The word Furcifer is derived from the Latin word “furci” or forked.
