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.

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.

The sighting by the two paddle boarders was the first confirmed sighting of a great white shark off Woods Hole in over two decades.
