Red-bellied lemur  (Eulemur rubriventer)

Believed to be one of the rarest Eulemur species, the red-bellied lemur exhibits the common traits of this genus, showing sexual dimorphism and moving quadrupedally through the trees (2). The long, dense fur of the upperparts of both males and females is a deep chestnut-brown colour, which is continued to the males' underparts (2). The females' underparts are creamy-white (2), and the characteristic ‘teardrop' patches of white bare skin under the eyes of the males is significantly reduced in the females (2) (5). These ‘teardrops' and the dense rich coat help to distinguish this medium-sized lemur from other species of Eulemur that occur in the same areaa. The fur around the males' ears is particularly dense, giving the head a squarish look, which is not as obvious in the females. The tail of both sexes is almost black, and the face and muzzle are dark slate-grey (2).
