Wildlife photographer Guy Edwardes snapped the pod of orcas as they hunted eider ducks off north-east coast of Scotland. For many unlucky birds known as Eiders, the looming black fin and gaping jaws of the killer whales were the last things they would see. The waters surrounding the Scottish islands are one of best places in Britain to catch a glimpse of orcas. Killer whales hunt in packs and can grow up to 32ft long and weight as ten tons.
