killer whales chased a terrified seal onto rocks near the town of Lerwick.Haydn Thomason, 27, was filming the orcas just by the coast at Greenhead on Shetland, when they suddenly began chasing the lone seal. The student, who also founded and runs Viking Fitness Training, explained that though he is lucky to have seen the magnificent creatures more than a few times living in Shetland, this was the first time he'd seen them this close.
