The common brown lemur has a total length of 84 to 101 centimeters, including 41 to 51 centimeters of tail. Weight ranges from 2 to 3 kilograms. The short, dense fur is primarily brown or grey-brown. The face, muzzle and crown are dark grey or black with paler eyebrow patches, and the eyes are orange-red.

Similar lemur species within their range include the mongoose lemur, ''E. mongoz'', in the west and the red-bellied lemur, ''E. rubriventer'', in the east. They can be distinguished from these species by the fact that ''E. mongoz'' is more of a grey color and ''E. rubriventer'' is more reddish. There is also some overlap with the black lemur in northeast Madagascar in the Galoko, Manongarivo and Tsaratanana Massifs. There is also overlap and hybridization with the white-fronted brown lemur, ''E. albifrons'', in the northeast portion of the common brown lemur's range.

Consistent with its large range, the common brown lemur occupies a variety of forest types, including lowland rainforests, montane rainforests, moist evergreen forests and dry deciduous forests. They spend about 95% of their time in upper layers of the forest and less than 2% of their time on the ground.

They normally live in groups of 5 to 12, but group size can be larger, especially on Mayotte. Groups occupy home ranges of 1 to 9 hectares in the west, but more than 20 hectares in the east. Groups include members of both sexes, including juveniles, and there are no discernible dominance hierarchies.

They are primarily active during the day, but can exhibit cathemeral activity and continue into the night, especially during full moons and during the dry season.

In the western part of its range, the common brown lemur overlaps that of the mongoose lemur, and the two species sometimes travel together. In the areas of overlap, the two species also adapt their activity patterns to avoid conflict. For example, the Mongoose Lemur can become primarily nocturnal during the dry season in the areas of overlap.

At Berenty there is a population of introduced ''E. fulvus rufus'' x ''collaris''. These lemurs show linear hierarchy, adult female dominance, and the presence of conciliatory behavior after aggressions. Additionally, stress levels decrease at the increase of the hierarchical position of individuals within the social group and reconciliation is able to bring stress down to the baseline levels.
Female common brown lemur - portrait, Andasibe, Madagascar Our last activity in the Andasibe area was to visit Lemur Island, as it was directly situated across our lodge. This concerns an artificial island separated from the main land by means of a canal, which you cross using a canoe.

It is very much a zoo-like experience where you can get very close to a small set of lemur species. They are so accustomed to people that they will jump on your head and backpack. 

Not a very authentic experience, but I was happy to learn that they made some sustainable changes compared to our visit years earlier. Several of the more sensitive lemur species are now situated at yet another island that you cannot visit, you can only see it in the distance.

The common brown lemur's mating season is May and June. After a gestation period of about 120 days, the young are born in September and October. Single births are most common, but twins have been reported. The young are weaned after about 4 to 5 months. Sexual maturity occurs at about 18 months, and females give birth to their first young at 2 years old. Life span can be as long as 30+ years.

The common brown lemur's diet consists primarily of fruits, young leaves, and flowers. In some locations it eats invertebrates, such as cicadas, spiders and millipedes. It also eats bark, sap, soil and red clay . It can tolerate greater levels of toxic compounds from plants than other prosimians can.
