A photographer captured an intimidating site as he parachuted off the coast of south Florida last week.

Photographer John Massung was flying over Sebastian Inlet on Thursday when he saw hundreds of sharks swarming just 100 feet from the beach.

Massung says he flew for about a mile down the shore and that the hordes of sharks never ended. A fellow photographer was even further out and saw the same scene.

Worst nightmare: A swarm of sharks was spotted off the coast of south Florida last Thursday

Stay out of the water: When the following pictures were posted to Facebook, users theorized that the swarm was a mix of Blacktip and Spinner sharks

Swarm: Blacktip and Spinner sharks migrate each year to breed in shallower waters

'It looked like they had traveling in mind. They were heading north,' Massung told NBC Miami.

Since he wasn't certain what kind of shark was gathering south of the inlet, Massung posted the photos to the Indian River by Air Facebook page to see if any experts could offer some enlightenment.

Most responded that the sharks looked like either Blacktips or Spinners, which migrate this time of year to breed.

The picture had been shared more than 2,000 times by Sunday. Massung says the sharks were still out in the water on Friday, but the conditions weren't clear enough to photograph the scene.
