Nauset Beach in Orleans was closed Sunday morning after a great white shark was spotted, WCVB reported.

The Cape Cod Times reported that a senior lifeguard spotted a dorsal fin about 150 yards off the beach at about 10:15 a.m.

The paper reported that the shark was estimated to be between 12 and 13 feet long based on the distance from the dorsal fin to the tail fin.

On Friday, another great white shark was spotted off the coast of Cape Cod.
