BOCA RATON, Fla. - Thousands of black-tip sharks, who spend the winter in Florida, are making their yearly migration north. That forcieda number of beaches along the Florida coast to shut down.

Experts say, despite the large number of predators in the water, there's no need to worry.

"This is pretty typical for this time of year," Shari Tellman, marine biologist with Florida Atlantic Universiaty, said. "Throughout February and the first half of March, that's when we see the most sharks coming through this area, Palm Beach County, specifically. They're a lot like snowbirds, they come down here and winter offshore, kinda in the service waters off the shelves of southern Florida and then they start heading north. So, they're just kind of hanging out down here throughout February, that's when we're seeing a lot of them, they're following the bait fish and then they're headed north. They're gonna head up to South Carolina and Georgia and up there there are estuaries where they find nurseries and that's where they mate and pup in the summer months."

Experts expect most of the sharks to be out of South Florida waters by April.
