Orcas caught on camera eating Great White SHARKS for the first time off the coast of South Africa

Killer whales have been caught on camera hunting and eating Great White Sharks for the first time, in an hour-long feeding frenzy. The extraordinary scenes were shot by both helicopter and drone pilots off the coast of South Africa, providing the first direct evidence of orcas preying on sharks. They reveal that the killer whales were attacking at least four sharks for about an hour, and that this unusual predatory behaviour might be spreading in the species. While a short drone video of the attack was released in June, a paper has been released this month analysing the clip plus all the footage taken from the helicopter. Scientists from the Marine Dynamics Academy studied the videos, and analysed drone and cage dive boat survey data before and after these predation events.
