A shark sighting off the coast of Cape Cod closed the popular Nauset Beach in Orleans on Saturday, but swimmers were already allowed back in the water the following day.

Shelly Negrotti, who snapped a terrifying photo of the shark tailing a kayaker, recalls the Jaws-like scene that unfolded as people scurried out of the water. "It was just like a chain reaction up and down the beach," Negrotti said. "We were all saying ‘Get in!' to the paddler as the shark was getting closer and closer."

Shark sighting have increased across the Cape in recent years as more and more seals — their prey of choice — have taken to calling the area home.
