WELLFLEET, Massachusetts: Dozens of dolphins were being kept away from shallow waters around Cape Cod by rescuers after 125 dolphins were stranded in the waters there a day earlier.

The International Fund for Animal Welfare said one group of ten Atlantic white-sided dolphins were found in a dangerously shallow area at dawn by swimming Teams in Massachusetts. They were herded into deeper water.

The organization said a second group of 25 dolphins was located swimming close to the shore near Eastham. Herding efforts were ongoing as the tide dropped.

Ten dolphins died during the stranding at The Gut - or Great Island - in Wellfleet, at the Herring River.

The organization said it was the largest mass-stranding on the Cape during its 26-year history there.

The team, first on foot, herded the creatures into deeper waters and then used three small boats equipped with underwater pingers.

More than 25 staff members from the organization and 100 trained volunteers were among the rescuers. Whale and Dolphin Conservation, the Center for Coastal Studies, AmeriCorps of Cape Cod and the New England Aquarium supported the rescuers.
