Cape Cod’s National Park Service says that around 10 a.m. the shark bit down on a swimmer’s board, who was about 30 yards away from the shore and in three feet of water. The swimmer was not hurt.

The beach was immediately closed and it will not open again until the area is deemed safe for swimmers. Officials say seals were spotted nearby.

Several marine crews are investigating, including the Atlantic White Conservancy.

On Monday, a great white shark attacked a seal within feet of Nauset Beach in Orleans, leaving a trail of blood in the water. The beach was closed for a period of time before later reopening.
