Fishermen are currently losing 5 to 10 percent of their yearly haul and fear the problem could become worse because whales who have mastered the technique are busily teaching it to others. The news seems to be rapidly spreading, as reports of similar fish-snatching are coming in from fishermen all over the world." (Ibid)
