Why Are Sharks Swarming in Florida?

Seeing one shark is enough to scare most swimmers out of the water. Seeing thousands of sharks in the water — and many leaping into the air as they hunt for prey — could be enough to keep a swimmer out of the water for life.

That's the scenario greeting beachgoers this week in Palm Beach County, Fla., where as many as 15,000 sharks are swarming in the area's warm shallow waters, the Palm Beach Daily News reports.

"They were practically right on the sand," lifeguard supervisor Craig Pollock told the Palm Beach Daily News. "They were frenzied and chasing bait all the way up to shore." Beaches around the area are now closed to swimmers.

Pollock identified the sharks as blacktip sharks (Carcharhinus limbatus) and spinner sharks (Carcharhinus brevipinna). Both species are renowned for leaping out of the water and "spinning" in the air as they search for the smaller fish that make up their diet.
