TRURO, Mass. — Yet another shark sighting in Truro closed Longnook Beach on Sunday.
A previous shark sighting in Truro on Saturday afternoon had closed a pair of local beaches for an hour, according to the town's Recreation and Beach Department.

Due to the sighting, Head of the Meadow Beach and Coast Guard Beach were closed for an hour between 1:30 p.m. and 2:30 p.m.
The town did not note what type of shark was spotted near the beach, though the Atlantic White Shark Conservancy called the fish a White Shark on their 'Sharktivity' app.
At 2:46, another shark sighting was reported, closing Head of the Meadow Beach for another hour.
Those sightings didn't stop one beachgoer, Matthew Mullaney, from enjoying the water once the beach was reopened. Mullaney's daughter, Hannah, however, says it's not worth the risk.
"They kept checking the water with binoculars and making sure before they let anyone back in," she said.
Both Ian Mouldey and his son Liam, however, say they know to keep close to the shore and keep a watchful eye.
"I get out of the water when I see seals so the sharks don't come," said Liam Mouldey, another beachgoer.
Just over an hour after Head of the Meadow Beach was closed for the second time, a White shark was seen swimming 150 feet away from the shores of Nauset Beach in Orleans, prompting the beach to close for an hour.
"You have to be aware, for sure, now with all the sightings and the attacks last year, you're definitely aware," said Ian Mouldey.
Researchers on Cape Cod launched a new study last month focused on the hunting and feeding habits of the region's great white sharks following last year's two attacks on humans, including the state's first fatal one in more than 80 years.
They hope the work contributes critical information to the ongoing debate over how to keep Cape beachgoers safe.
