Pygmy mouse lemur (Microcebus myoxinus), also known as Peters' mouse lemur or dormouse lemur, is a primate weighing only 43–55 g (1.5–1.9 oz); it is the second smallest of the mouse lemurs. Its dorsal side is a rufous-brown colour, and creamy-white ventrally. It lives in dry deciduous forests. 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 (Mirza coquereli).
