A spectacular shark feeding frenzy Monday off Perth, Australia, led to the closure of area beaches as a precautionary measure.
The event, which occurred about 2,000 feet beyond Yanchep in northern Perth, was videotaped by the crew of a sea rescue helicopter (video is posted above). Footage shows dozens of blacktip and bronze whaler sharks during a frenetic assault on schooling bait fish and small tuna.
It was a natural event but because it occurred so close to shore and involved so many sharks, beaches in the vicinity were temporarily closed.
"You normally don't see them in this number," Chris Peck, of Surf Live Saving WA, told The Australian. "Where there's bait fish, there's usually two or three of them."
The sharks measured to about six feet.
