It's unclear exactly what is attracting the sharks and great whites to our beaches and it's causing families to take extra caution when chosing which beach to go to.

WCVB reports that beach goers are being warned of an unconfirmed shark sighting close to Duxbury Beach.

According to the Duxbury harbormaster, the sighting was reported in the waters close to  Ocean Road North.

The Atlantic White Shark Conservancy announced the tagging of an 11-foot great white off Chatham this past Thursday.  That makes eight, the total number of sharks tagged so far this season.
