Rare footage captured by drone of a pack of killer whales hunting a 9-foot great white shark recently aired during Discovery's Shark Week. In the video, two orcas can initially be seen maneuvering in South Africa’s Mossel Bay, when a third whale surfaces with the dead shark in its jaws. Researchers noted the whale bit the shark around the area where its liver is located. Marine biologist Alison Towner called the clip, "one of the most incredible pieces of natural history ever captured on film."
