A mysterious illness that causes starfish to rip themselves apart has marine scientists baffled. The mystery condition has affected starfish up and down the west coast, mainly near Washington state.
The illness causes starfish to develop lesions on their bodies. The disoriented starfish twist their arms into knots. The arms then crawl away and rip apart from the bodies causing the insides to spill out. Without arms the starfish die within 24 hours. And, unlike most starfish, the arms don't regenerate.
