A Sumatran slow loris (Nycticebus coucang) at the Bandar Baru Rehabilitation Centre, in north Sumatra, Indonesia. The Sumatran slow loris has become one of the 25 most endangered primates in the world due to hunting and loss of forests in Indonesia. The one here was kept as a pet and was seized from its owners.
