Mysterious Disease Turns Starfish to ‘Slime’ on U.S. West Coast | Scientific American

Scientists are searching for the root of a disease that is causing starfish all along the West Coast, from Alaska to Southern California to essentially turn to slime. Though the disease has been reported before, it has only been in small numbers and localized in the Southern Californian region.
