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!
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
The word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.
The chameleon tongue accelerates towards its target at over 1642m per second. Chameleons rarely miss their intended food item.
Chameleons have a very poor sense of smell.
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
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.
Trioceros schubotzi can be found at elevations as high as 4500m.
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.
