Aerial footage provides proof of orcas killing great white sharks

Scientists have published new findings confirming that orcas hunt great white sharks, after the marine mammal was captured on camera killing one of the world's largest sea predators.

A pod of killer whales is seen chasing sharks during an hour-long pursuit off Mossel Bay, a port town in the southern Western Cape province, in helicopter and drone footage that informed a scientific study released this week.

"This behavior has never been witnessed in detail before, and certainly never from the air," said lead author Alison Towner, a shark scientist at Marine Dynamics Academy in Gansbaai, South Africa.
