Otters off the coast of South Africa have been caught catching sharks and eating their hearts, livers and male sex organs before discarding the rest of the body.

Shysharks are one of the most abundant species living in the Table Mountain National Park marine protected area - where the Cape clawless otters also reside.
The shyshark is a species of catfish that lives in temperate waters and are very common - found near the bottom of sandy or rocky habitats.
They feast on crustacians and seagoing worms, but are prey to larger sharks, seals and now - it seems - otters as well.
Dr Kock told Newsweek that when there is an abundance of food, certain predatory species have evolved to cherry pick the most nutritious parts of their prey.
They select parts of the body that can optimise their fitness - as well as otters, bears, seals and killer whales have evolved to do the same thing.
In False Bay there have been there have been several cases of great white shark carcasses found with their livers missing - in that case it
