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.

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

Teenage paddleboarders enjoying the waters in Cape Cod on the Fourth of July had an unexpected — and unwanted — visit from a great white shark. Margaret Bowles told CBS News that she had been paddleboarding with her bestfriend Madeleine Cronin for a few hours near Stony Beach when the terrifying experience occurred.
