Forget swimming off South Florida's coast for a few days.

Tens of thousands of sharks are in the waters, some just a few feet from shore.

They're heading north in their annual migration, and their travel plans have temporarily closed beaches for a 50-mile stretch from Jupiter south to Boca Raton.

The most commonly spotted sharks are spinners and blacktips, but hammerheads, tigers, lemons and bull sharks also have been seen.

A shark is a shark.

Stay out of the water.
