Stunning new footage captures the moment adult orcas carefully teach their calves how to hunt, demonstrating how to push a seal off a bit of ice before getting the young to give it a go themselves.
The clip shows a group of seven orcas — four adults and three calves — as they circle a seal on a tiny chunk of ice in western Antarctica’s Marguerite Bay. The lesson, which lasted over an hour, was filmed for the new PBS show "Nature: Expedition Killer Whale," which follows a remarkable group of pack ice orcas (Orcinus orca) that live off the coast of Antarctica.
