Remarkable video shot north of the Australian city of Perth shows approximately 50 sharks engaged in a feeding frenzy.
The sharks, some of which were estimated to be up to 2.5 meters long, were feeding on a school of tuna.
BBC News reports that the feasting predators included black tip whalers, bronze whalers and spinner sharks.
A scientist from the Australian Department of Fisheries told local media that the event was unusual only in that it happened so close to shore, according to Britain's Daily Telegraph.
Nearby Yanchep beach was just 700 meters away from the animals -- it was closed to swimmers for two hours before being deemed safe.
