For Cape Cod regulars, shark sightings have becoming something of a regular occurrence.
However, all it takes is a dorsal fin to poke its way up above the water to draw a both terrified and curious crowd at the beach.
Lisa Bogush of Burlington, CT said she and her family were vacationing in Provincetown when her stepson, Jacob Roberts, captured one such sighting on camera.
Bogush said Roberts took the photos at Herring Cove Thursday night.
She said the visit was enough to get everyone out of the water.
She judged that the animal was about 20 yards off shore and looked to be between 10 and 15 feet long.
Researchers said there have been more than a dozen great white shark sightings at the Cape earlier this month. They said they're following the seals, one of their primary sources of food.
CBS News reported that two Cape Cod beaches closed after visitors spotted a great white shark biting a seal. Beachgoers saw the attack at Nauset Light in Eastham on Wednesday.
As a result, officials suspended swimming at both Nauset Light and Coast Guard beaches.
Officials in Cape Cod call it standard operating procedure.
