Orca School

It's a rare and truly amazing sight to witness. Off the coast of Argentina, a pod of orcas can ride a wave to shore, seize their prey off the beach and then slide back into the water with their kill. Mastering this skill takes years of practice, and is so dangerous that fewer than half of these orcas attempt it. Nat Geo follows two of the masters, Mel and Maga, as they feed on up to 16 sea lions a day and through rigorous training, pass this extraordinary hunting talent on to their offspring.
