metro.co.uk A Morrisons shopper has been left shocked after discovering a tongue-eating bug in his fish supper. Paul Poli, a 62-year-old retired headmaster, was about to enjoy a tasty sea bass when he discovered the unpleasant creature dwelling inside the fish. After returning the sea bass to the store in Swansea, South Wales, the creature was identified as cymothoa exigua, commonly referred to as the tongue-eating louse.

Mr Poli has said that the discovery of the parasite has put him off eating fish for life.
