Thousands of sharks swarm beaches

Authorities close a stretch of beach in Florida as thousands of migrating blacktip sharks come close to shore. Deborah Lutterbeck reports.

SEVERAL South Florida beaches have reopened after the migration of thousands of sharks led to precautionary closures.

The Palm Beach Post reports three Palm Beach County beaches have reopened, though unseasonably chilly temperatures likely will keep most swimmers away anyway.

Intermittent closures are still possible. When sharks are spotted near shore, lifeguards close beaches for at least a half-hour.

Craig Pollock, a lifeguard superviser at Midtown Beach, said it was the first time he'd seen the sharks out in such huge numbers.

"We got here this morning and they were thick, really thick," Pollock said. "They were frenzied and chasing bait all the way up to shore. They were practically right on the sand."
