A `cute` primate so rare it was thought to be extinct has been caught on camera in the forests of Sri Lanka for the 1st time

The Horton Plains slender loris is a small, nocturnal animal which can grow up to 17 centimetres (six inches) long with big, bulging eyes.

Endemic to Sri Lanka, it was first discovered in 1937 but had only been seen four times since then.

Scientists last caught a glimpse of the primate in 2002, and believed the elusive animal had since died out.
