Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
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.
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
Chameleons can project their tongue up to 2.2 times their body length.
The word Chamaeleo is derived via Latin from the Greek word khamaileon. It roughly translates to ground lion. Khamai means on the ground and leon means lion.
The word Calumma comes from the Latin word for covering. This genus consists of chameleons from Madagascar with occipital lobes.
The word Furcifer is derived from the Latin word “furci” or forked.
Chameleons have acrodont teeth meaning they are an extension of the jawbone. They are not set in sockets nor are they replaced.
