A record 129 common dolphins have stranded themselves over three weeks along the coast of Cape Cod, Massachusetts.
A marine mammal specialist told CNN on Monday it was the Northeast's largest "single-species event" of its kind on record.
The New York Times reports that while this isn't a new problem, most strandings end within two days -- this time it has carried on for almost a month with no end in sight.
MSNBC reports the dolphins oddly seem to be healthy. While common dolphins are "known to strand in groups due to their tight social structure," the unusually large numbers have prompted investigation of factors such as tides and weather.
