An endangered and secretive mammal that's rarely seen in the wild has been caught on camera!
The pygmy hippo - which is a smaller version of the normal hippo - was seen in the west African country of Liberia.
There are thought to be less than 3,000 left in the wild and there's concern for their future because of poaching and their habitat being destroyed.
Experts have set up special hidden cameras to monitor the rare animals to see how many are left.
There were fears that the number of pygmy hippos might have decreased because of the knock-on effects of two wars in Liberia.
Dr Ben Collen, who led the expedition, said: "We were delighted to discover that a population still persists there, but remain highly concerned for the species, which continues to face significant threats from poaching and habitat degradation."
