Killer Whale Hunts And Eats Great White Shark Off The Coast Of South Africa.

A solitary killer whale, or orca, has been filmed hunting and killing a great white shark in an "astonishing" attack off the coast of South Africa.

Scientists said it was "unprecedented" and showed the exceptional predatory skills of killer whales.

Two orcas in particular off South Africa's coast have been observed before working together to hunt and kill sharks, including great whites.

Dr Alison Towner, a marine biologist from Rhodes University in Grahamstown, South Africa, led the study.

"This caught us off guard," said shark biologist Dr Towner.
