Anglers fishing off the coast of Ocean City, Mary., got a thrill on Monday when a huge great white shark swam up to their boat and circled for 15 minutes.

“She showed up and every bit of 15- to 18-foot long, 2,000 to 3,000 pounds – just a massive animal,” Steven White, who recorded the video of the shark, told WBAL TV, a Baltimore NBC affiliate.

“What an incredible experience to be on that boat,” said Jennie Janssen, who works with the Baltimore Aquarium.

“It’s a once-in-a-lifetime experience,” said White.
