— -- Video shot from an oil platform off the coast of Louisiana shows hundreds of migrating sharks.
The footage shows the sharks heading north after migrating south for the winter, according to Fox station WVUE in New Orleans.
The sharks follow other fish that they eat as the fish move into warmer waters, shark expert Greg Marshall said, according to WVUE.
The video was taken about 30 miles off the coast of Grand Isle, Louisiana, last week. The oil platform sits about 70 feet above the surface of the water.
