They say a picture is worth a thousand words and a photograph of a shark taken by two teenagers in Massachusetts last weekend certainly tells a story.  This photo taken off Woods Hole on Cape Cod on July 4th shows a great white shark just feet away from Margaret Bowles on a paddleboard - and she didn't know it.

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.

"The sharks and the humans are both on the water's edge more frequently in the summer," said Dr. Nick Whitney, senior scientist at the New England Aquarium.
