This incredible footage has been doing the rounds on the internet recently. It shows how a fisherman in Australia, who had been treading water for twenty hours since his boat sank, is rescued just in the nick of time.
Not only is the man exhausted, but there are also a great number of sharks circling him, including hammerheads.
Unfortunately, at the time of the broadcast, it was confirmed that one of his fellow fishermen did not survive and one is still missing. Our thoughts are with their family and friends at this tragic time.
