Shark Feeding Frenzy PerthBeaches off Perth, Australia were closed today due to a helicopter crew’s sighting of a massive shark feeding frenzy.

Video footage shows dozens of sharks in a crazed assault on schooling bait fish and small tuna.

The feeding frenzy took place about 2,000 feet beyond Yanchep in northern Perth.

Chris Peck, of Surf Life Saving WA, said many beaches were closed Monday mainly as a precaution.

“You normally don’t see them in this number,” Peck said. “Where there’s bait fish, there’s usually two or three of them.”

Shark researcher Rory McAuley added that this type of event probably happens fairly often, but much farther offshore.

“But it is quite unusual to see it so close to shore, and it is unusual to see it within the bounds of the major metropolitan area,” he said.
