Sanford's brown lemur  (Eulemur sanfordi)

This medium-sized lemur has a horizontal posture, which is suited to its predominantly quadrupedal mode of movement (2). These lemurs are also capable of leaping considerable distances, their long furry tails assisting them in maintaining their balance (5). Both sexes are dark brown, with a lighter underside and darker areas at the end of the tail. However, females are a reddish-brown while males are more grey-brown in colour (2) (5). The most distinctive difference is the existence of a pronounced creamy-grey beard and prominent ear tufts in the male, that are lacking in the female, which give the male a ‘maned' appearance. The male's nose bridge and snout are black, while the female's face and head are completely grey (2).
