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.

In this handout picture released by Awashima Marine Park, a 1.6 meter long Frill shark swims in a tank after being found by a fisherman at a bay in Numazu, on January 21, 2007 in Numazu, Japan. The frill shark, also known as a Frilled shark usually lives in waters of a depth of 600 meters and so it is very rare that this shark is found alive at sea-level. Its body shape and the number of gill are similar to fossils of sharks which lived 350,000,000 years ago. (Photo by Awashima Marine Park/Getty Images)

A June 11, 2009 file photo provided by Elasmodiver shows scientist Eric Hoffmayer of the University of Southern Mississippi's Gulf Coast Research Lab in Ocean Springs, Miss., taking fin measurements of a whale shark in the Gulf of Mexico, about 55 miles off the Louisiana coast. Hoffmayer says whale sharks, the world's biggest fish, are particularly vulnerable if they get into the oil slick. That's because, rather than moving up to the surface and down again, they eat by swimming along the surface, sucking in plankton, fish eggs and small fish. (AP Photo/Elasmodiver, Andy Murch, File)

In this picture taken on September 3, 2011, an environmental activist releases a baby black-tip shark into the sea as part of an operation organised by the sharks protection group Dive Tribe off the coast of the southern Thai sea resort of Pattaya. On average an estimated 22,000 tonnes of sharks are caught annually off Thailand for their fins -- a delicacy in Chinese cuisine once enjoyed only by the rich, but now increasingly popular with the wealthier middle class.
