Seven Atlantic white-sided dolphins were rescued by dozens of staff at the International Fund for Animal Welfare, interns and trained volunteers in Welfleet, Massachusetts, on Wednesday morning.

IFAW was notified early Wednesday that at least three dolphins were stranded in what they said was a shallow part of the Herring River.

“Welflit is a common place for mass events stranded because of its hook-shaped shape within the Cape Cod coastline and because of the large tidal fluctuations in Cape Cod Bay,” the IFAW press release said.

“The dolphins looked alert and in good health, but the day was sunny and warm, and we needed to move fast,” said Misty Niemeyer, an IFAW animal rescue worker and marine mammal research team.

“Our team has faced increasing difficulties in raising water, but we know from experience that dolphins cannot be left in this area because they often fall into a repetitive cycle of tides,” Niemeyer said.

The group said dolphins, most likely all juvenile males, were about 6 to 8 feet long, and the largest weighed about 250 pounds.

The IFAW team said they used cooling blankets for dolphins, which, when soaked in water, maintain a healthy animal body temperature in hot weather.

All seven dolphins were taken to Herring Cove Beach in Provincetown and released in chess time between 1:30 and 2 p.m.

“In the coming days, IFAW will monitor the progress of the pod through the satellite of one dolphin,” – said in IFAW.
