Two teens were taking a photo while paddleboarding off the Cape. They didn't realize a shark entered the picture.

A great white shark shocked two Massachusetts paddleboarders as it swam just feet away from the two friends enjoying their Fourth of July evening on the water. College students Margaret Bowles and Maddie Cronin were paddling in the waters off Woods Hole on the southwest end of Cape Cod when they saw the predator’s estimated 8-inch fin.

As Cronin, 18, snapped photos of Bowles, 19, around 7:30 p.m., a great white shark moved through the water nearby, its dorsal fin slicing through the surface.
