Richard West, a 35-year-old fisherman living in Plymouth, found the plastic toy on the top of his fishing nets 20 miles (32km) south of Penzance on Tuesday.

He contacted the project Lego Lost at Sea, whose founder Tracey Williams confirmed the piece to be the first-ever reported shark from the 51,800 Lego sharks lost off the Tokio Express cargo ship on 13 February 1997.
