Elusive endangered monkeys caught on camera in Borneo

One of the world's most endangered primates has been caught on camera by scientists on the island of Borneo.

Using time-lapse recordings to investigate the diversity of the remote Wehea forest, the team were surprised to see an unusual sub-species.

Close analysis confirmed that they had photographed a group of Miller's grizzled langurs.

Fears for the monkeys' future were sparked last year when none were recorded in previously known habitats.

The international team of researchers suggest their evidence could indicate a more optimistic future.
