Rescuers struggled in cold, windy weather and rough water trying to help keep dozens of dolphins alive after the animals stranded themselves on a Florida Panhandle beach.

About 30 roughtooth dolphins, a species not normally found in shallow water, managed to swim back out into the Gulf of Mexico on Sunday, while 29 were trucked to a boat basin on Cape San Blas, a narrow, hook-shaped peninsula that juts into the gulf about 75 miles southwest of Tallahassee, said sheriff’s Capt. Joe Nugent.

Of the approximately 60 dolphins, about a dozen are known to have died.

Members of the public and even prison camp inmates waded into 62-degree water Sunday to join in the rescue effort along with personnel from government and rescue agencies.
