This stunning video of a humpback whale mating contest in Northern Tonga is just one example of how the new BBC/Discovery Channel series Life captures the drama of our world topside and below. The 11-episode series debuts on June 1. In order to capture what Life producer Ted Oakes calls ?the largest battle in the animal kingdom,? the show's camera crews filmed from helicopter, by boat and through scuba diving. ?Perhaps the hardest and most terrifying thing was getting the divers in position to film the whales underwater,? Oakes says. ?This involved moving alongside the pack of charging whales and placing a diver in front of the pack. ?The divers couldn't use tanks,? Oakes continues. ?The behavior of whales is disrupted by the bubbles created from scuba diving, and so the divers actually had to free dive with the whales.? Another scene from Life required more than 100 dives under 8 feet of ice in Antarctica.
