Mysterious epidemic devastates starfish population off the Pacific Coast - and East Coast

Up and down the Pacific Coast, starfish are dying by the tens of thousands and no one knows why. "Reports have since surfaced from Southern California to as far north as Alaska. At first, only a certain species known as the sunflower star seemed to be affected. Then it hit another species, then another. In all, about a dozen species of sea stars are dying along the West Coast. It’s been coined sea star wasting syndrome, and it’s also been reported at sites along the East Coast."
