Trioceros schubotzi can be found at elevations as high as 4500m.
Chameleons have a very poor sense of smell.
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
The smallest chameleon species is Brookesia micra with an adult length just over 1 inch (29mm). It hatches from an egg no bigger than a grain of rice!
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.
The oldest known chameleon fossil is from the extinct species Chamaeleo caroliquarti. It was found in Europe and is 26 million years old.
Chameleons have a high midichlorian count.
Pygmy chameleons are sometimes referred to as False Chameleons. This term is actually incorrect and is in reference to anoles, particularly the Cuban False Anole.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
