Beaches in Florida have been closed as a huge school of sharks swam close to the shore during their annual migration.

Thousands of Black Tip and Spinner sharks are heading north up the Atlantic coast.

All along the route, people are being banned from the sea, just as the annual Spring Break holidays reach their peak.
