The killer whale's name could not be more suitable. With its razor-sharp teeth and fear of no other creature, the sleek black-and-white orca is at the top of the aquatic food chain thanks to its extraordinary predatory behaviour. As this documentary reveals, they live and hunt together in family groups, herding fish into small areas so they are easier to eat, using their distinctive fins to cause small waves which knock prey off ice floes and into the water, or surrounding much larger animals, chasing, biting and wearing them down until they become another meal.
