I took this photograph of this surfer yesterday at Nauset Beach in Orleans on Cape Cod. It was bitterly cold ( in the 20s and very windy) so I did not get a good one of him standing up, just sitting… waiting for that perfect wave.

When I got home and was looking at my photographs, I saw something in the water to the left of the surfer. It looks like a huge fish! Could it be a shark? What other kind of large fish would be in these cold waters this time of year?

Or… does anyone have any other ideas as to what it could be?
