There’s a plague currently afflicting starfish along the North American West Coast. Called sea star wasting disease, it’s a terrifying affliction that causes echinoderms to tear themselves apart. Now, for the first time ever, the disease has been spotted in northern waters—a possible consequence of global warming.
Starfish may be flexible, but they're also tough. Yet a mysterious "wasting syndrome" is making starfish from Southern California to Alaska decay while still alive. Populations are being decimated up and down the west coast.
