The Ocean's Greatest Predators. In the wild orcas - commonly known as killer whales - are the ocean's greatest predators. Highly social and highly deadly they dominate the aquatic food chain. Killer Whales follows a team of wildlife experts as they span the globe to examine the astonishing predatory behaviour of this opportunistic feeder. On their epic journey the team travels to Patagonia Argentina where the orcas launch themselves onto the beach to capture sea lion pups; visit South Africa where killer whales have just been discovered hunting their closest cousins dolphins; and finally head to New Zealand where the orcas take on poisonous stingrays. Along the way they witness firsthand how this incredible creature rules the seas with strength speed and social intelligence. Thanks to their new research and stunning photography the world of the orca is revealed as never before.
