The animals were caught on by a camera trap set up by Fauna & Flora International (FFI) in partnership with the Zoological Society of London (ZSL) and the Forestry Development Authority of Liberia.

"We know surprisingly little about the nocturnal and secretive pygmy hippo," explained Dr Chloe Hodgkinson, Liberia Programme Manager at FFI. "These camera surveys provide us with vital insight into the ecology, behaviour and distribution of this species.

"This information is extremely important, as it will help us design an effective conservation plan to ensure the survival of the pygmy hippo.

"With only around 2,000 left in the wild, it is now a race against time.”"
