Silvery Lutung

The silvery lutung, also known as the silvered leaf monkey or silvery langur, is an Old World monkey that lives in trees in coastal, mangrove and riverine forests in Sumatra, Borneo and Java and parts of the south-western Malay Peninsula, the Natuna Islands and other nearby islands. It is the type species of its species group (Wikipedia, general species account).

It is a medium-sized monkey with a long, non-prehensile tail, and grey-tipped dark brown or black fur that gives it a uniform silvery appearance (Wikipedia, general species account).
