Sushi king pays record $3.1m for endangered bluefin tuna in Japan

The winning auction bid for the enormous tuna was more than double the price fetched five years ago

A record $3.1 m (2.4 m) has been paid for a giant bluefin tuna at Tokyo's new fish market, which replaced the world-famous Tsukiji late last year.

The winning bid for the prized but endangered species at the predawn auction was more than double the 2013 annual New Year auction.
