Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
The word Calumma comes from the Latin word for covering. This genus consists of chameleons from Madagascar with occipital lobes.
The process of shedding is called ecdysis.
Furcifer labordi (Labord’s Chameleon) has the shortest lifespan of only 4-5 months. It also has the shortest lifespan of any tetrapod!
Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
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!
The word Bradypodion comes from the latin “bradus podos” or slow foot.
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.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
