Rare Shark Feeding Frenzy at Cape Lookout National Seashore, North Carolina

Some people are calling it a real-life sharknado. This is the moment Donnie Griggs and his friends at the One Harbor Church in North Carolina saw a shark feeding frenzy at the Cape Lookout National Seashore. Donnie told Storyful he is "an avid waterman who spearfishes, dives, swims and surfs at Cape Lookout often". He also said this was a rare occurrence and that the North Carolina beaches are safe for swimming. (Footage By Facebook/Donnie Griggs/Storyful via Getty Images)
