Stunning drone footage shows a huge shoal of fish scatter when sharks attacks.

The clip, which was filmed on Friday (October 11) off the coast of St Petersburg, Florida, shows the massive group of crevalle jacks repeatedly disperse as several sharks attack.

"The sharks made a few passes through the school of jacks before they gave up and moved on," said the filmer.

"Jacks are among the fastest fish in the ocean and are very impressive predators," he added.
