![A trained volunteer attempts to herd stranded dolphins into deeper waters on Friday in Wellfleet, Mass. As many as 125 Atlantic white-sided dolphins became stranded Friday on Cape Cod and at least 10 died, prompting an intensive rescue effort, according to the International Fund for Animal Welfare.](https://npr.brightspotcdn.com/dims3/default/strip/false/crop/1340x1005+86+0/resize/1340x1005!/?url=http%3A%2F%2Fnpr-brightspot.s3.amazonaws.com%2Fd1%2F25%2F5d5afc484790bcb78139e0c896e0%2Fap24180808942240.jpg)
The area is the site of frequent strandings, which experts believe is due in part to its hook-like shape and extreme tidal fluctuations. Ten dolphins died in a mass stranding on Friday.
