Everyone’s keeping their eyes peeled for sharks on the Cape.
On Thursday, it was state police troopers aboard a helicopter who spotted a shark swimming off a Provincetown beach.
The ocean predator was about 30 yards off Race Point Beach, and police said the troopers used the helicopter’s P.A. system to urge beachgoers out of the water.
According to WCVB, Race Point Beach was closed Thursday afternoon to swimmers after a shark was seen devouring a seal about 10 to 20 yards from shore.
A beachgoer captured the grisly meal on video.

Both Longnook and Coast Guard beaches in Truro were also closed on Thursday due to shark sightings.
The heightened awareness of the sharks swimming in Cape waters follows after a 61-year-old New York man was bitten by one while wading along Longnook Beach in Truro on Wednesday. William Lytton, 61, of Scarsdale, N.Y., was airlifted for treatment of deep puncture wounds to his torso and leg. As of Thursday, he remained in serious condition.
Lytton is the first person to be attacked by a shark off the coast of Massachusetts since 2012.
Researchers with the Atlantic White Shark Conservancy continue to urge swimmers on the Cape to be “shark smart” and use the research group’s free app, which provides information on white shark sightings and movements.
As of Friday morning, the map showed that over the last 48 hours about 18 sightings or detections of sharks off the Cape had been reported.
