A Common brown lemur, (Eulemur fulvus).

The Common brown lemur Eulemur fulvus is a medium-sized quadrupedal Lemur. In the wild, it is found only on the island of Madagascar, some smaller islands off the coast and the island of Mayotte in the Comores.


Two male brown lemurs near the island of Nosy Be.

The common brown lemur is a diurnal Primate that has a head body length of approximately 43 – 50 cm and a tail length of around 41-51 cm[1][2][3]. Weight ranges between approximately 3 and 3.5 kg[3]. Coat color is brown to grey brown on the back while the ventral coat is paler [3]. The face, muzzle and top of the head are typically black while the beard tends to be lighter [3]. Patches of light fur above the eyes are not uncommen. In the northern part of the range and on the island of Mayotte some animals exhibit larger light patches over and around the eyes. There are no size or color differences that distinguish males from females.


Group size varies between 3 and 12[2][3]. The common brown lemur moves mostly quadrupedally but is also a reasonably adept leaper[3].


The common brown lemur is frugiverous but also eats young leaves and flowers [2][3].

Geographical distribution

The common brown lemur may be found throughout western Madagascar north of the Betsiboko River, in scattered forest fragments in eastern madagascar, to the north on islands around Nosy Be and on the island of Mayotte in the Comores[3].

Two color variants of the brown lemur - the Mayotte form on the right and the more common color variant on the left.


The common brown lemur is considered to be vulnerable by the IUCN.
