A New Zealand fisherman is lucky to be alive after the barb of a stingray severed an artery in his leg. The barb from the stingray pierced the leg of Gavin Scoles, 43. He suffered excruciating pain and lost almost a quarter of his blood before having surgery at Auckland Hospital. Mr Scoles pulled out the barb and the crew applied a tourniquet and called emergency services who sent the Westpac rescue helicopter. Scoles was fishing off Mercury Island with two others on his boat when a stingray became tangled in a net.
