A Cape Cod Beach has been closed down after a lifeguard spotted a great white shark off the coast.
Orleans Harbormaster Dawson Farber told the Cape Cod Times the lifeguard spotted a dorsal fin about 150 yards from Nauset Beach around 10:15 a.m. on Sunday.
Swimmers were advised to get out of the water when the fin was sighted. The shark is believed to be between 12 and 13 feet long and it was swimming in the direction of Chatham.
Narragansett Bay Keeper Tom Kutcher of Rhode Island Save the Bay says with the increase in seals in the Rhode Island and Massachusetts area it is likely to attract sharks to the area. A great white shark has not been sighted off of any of Rhode Island's beaches this season.
However the Rhode Island coast is no stranger to great whites. According to Kutcher the largest great white shark ever caught was caught between Point Judith and Block Island.
In 2012 the body of a great white shark washed ashore in Little Compton.
While great whites are not overly common to Rhode Island waters the growth of the seal population in Rhode Island and Massachusetts attracts great whites to feed.
If anyone sights a great white shark they are advised to report it to officials and to get out of the waters.
