text:  Rescuers are struggling to save dozens of dolphins who are stranded in shallow waters right near the Herring River in the Cape Cod area of Massachusetts. The International Fund for Animal Welfare says they're trying to herd the dolphins into deeper water, but the humans are getting stuck in deep mud along the river's bottom. They don't know why the dolphins have been stranding themselves, and so far they've only managed to get 10 of them into deeper, safer water. I'm Debra Valentine. This is Fox News.
