White-belted ruffed lemur

White-belted ruffed lemur Varecia variegata subcincta (EEP)

As their name suggests, white-belted ruffed lemurs have a band of white hair in the middle of their uniformly black backs. This distinguishes them from their cousins the black-and-white ruffed lemurs, whose backs but not shoulders are covered with white hair.
 
Up to about 15 white-belted ruffed lemurs make up fission/fusion groups, meaning they break off into smaller units when food is scarcer. These small groups aren’t fixed and can also split up then get back together.
 
Almost wholly frugivorous and very fussy, white-belted ruffed lemurs are highly sensitive to disruptions in their environment. They are also among the most hunted lemurs, due to the popularity of their meat.
 
When taken unawares by predators, white-belted ruffed lemurs warn other members of their group by means of loud yelps.
