Pygmy Mouse Lemur (Peters’ Mouse Lemur)

The Pygmy Mouse Lemur, Microcebus myoxinus, also known as Peters’ Mouse Lemur, is the smallest primate in the world. Its small size and nocturnal nature made it difficult to locate for over a century, and was rediscovered in the Kirindy forest in western Madagascar in 1993. They are believed to inhabit other parts of the island, but so far have only been discovered in a localized area. It lives in dry deciduous forests.

The smallest of all mouse lemurs, the Pygmy Mouse Lemur measures only about 2.44 inches tall and weighs roughly 1 ounce. Its dorsal side is a reddish-brown color, and creamy-white ventrally. The lemur rests during the day, and it has a tendency to sleep in the open, which increases the risk of predation; although this danger is somewhat mitigated by sleeping alone. It can also use the abandoned nests of the Coquerel’s Giant Mouse Lemur.
