The word Brookesia is named after the British naturalist Joshua Brookes.
Trioceros schubotzi can be found at elevations as high as 4500m.
Chameleons can project their tongue up to 2.2 times their body length.
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.

The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
Some chameleons play dead to avoid predation; this is called thanatosis.
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
The word Calumma comes from the Latin word for covering. This genus consists of chameleons from Madagascar with occipital lobes.
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.
