WELLFLEET (AP) — Animal welfare officials have rescued four more dolphins that stranded on Cape Cod over the weekend.
A spokeswoman for the International Fund for Animal Welfare says the dolphins got trapped Sunday in the Herring River in Wellfleet, but were successfully moved to the deeper, open waters off the shores of Herring Cove Beach in Provincetown by about 8:30 p.m.
That came after two dolphins were rescued on Saturday.
The organization says 129 dolphins have stranded since Jan. 12. Of those, 92 have died and 37 have been successfully released.
Scientists are trying to figure out why so many dolphins are beaching in the Cape.
