‘Sharktivity,’ the Atlantic Shark Conservancy’s great white shark spotting website, reported a confirmed great white shark sighting a short distance north of Penikese Island Sunday.

That would have put the shark about six miles southeast of Westport’s Gooseberry Neck and a short distance north of Cuttyhunk Island.

The Boston Globe reported that David Cody and his son, Paul, shot a video of the shark as it swam up to their boat.

"It was big. It looked big to us," David Cody told the shark network. An expert from the New England Aquarium later confirmed that the shark in the video was a great white.

Great whites are unusual in Buzzards Bay but turn up from time to time. Among the most photographed was one that somehow got itself stranded in a small lagoon near Hadley Harbor (at the other end of the Elizabeth Island chain off Woods Hole. The shark, estimated at 15 feet long, swam about for over a week while Mass. Division of Marine Fisheries provided protection from curious visitors. A tag was attached to the shark which finally made its way out after over a week.
