ulemur fulvus is a medium-sized lemur with a head-body length of 43–50 cm, a tail length of 41–51 cm, an overall length of a little more than a meter, and a body weight of 1.7–2.1 kg (C. Schwitzer, pers. obs.). Males and females are similarly colored. The dorsal coat is brown to gray-brown and the ventral coat is paler, tending toward gray. The face, muzzle and crown are dark brown to almost black, the beard is lighter, and patches of light fur above the eyes are variable. Animals in the northern part of this lemur’s range have large light patches over the eyes, while the eye patches of animals from more southerly populations may be barely discernible. The eyes are orange-red. In the field, E. fulvus is most likely to be confused with the mongoose lemur (Eulemur mongoz) in the west and the red-bellied lemur (E. rubriventer) in the east, especially if only a fleeting glimpse of the animal is obtained. \([\dots]\) https://lemursofmadagascar.com
