Save: Two rescued common dolphins are kept warm with blankets after beaching on a Cape Cod shore
At least 20 dolphins have died after they were washed up on several Cape Cod beaches, according to an animal welfare organization.
More than 40 dolphins have been found stranded close to the shore since Thursday and the number is likely to rise.
Kerry Branon of the International Fund for Animal Welfare says the common dolphins were found in Dennis, Brewster, Orleans, Eastham and Wellfleet on Saturday.

Location: Between 40 and 50 dolphins have been found stranded close to shores near Cape Cod, Massachusetts
She says of the 28 to 30 dolphins found, 10 to 12 have died and eight were inaccessible to rescuers. They later died.
Almost 20 dolphins have been saved.
She told CNN: 'It may not sound like a high success rate, but when you consider that 27 were alive when they washed up, I think we're doing pretty well.'
The dolphins are two of at least 28 dolphins that stranded along Cape Cod Bay's shores from Dennis to Wellfleet.
