Sea stars (starfish) along North America’s west coast have been dying at an alarming rate. A syndrome known as sea star wasting disease causes the animal to lose limbs and eventually disintegrate, leaving behind a pile of white goo. Scientists researching the disease have identified a likely culprit, a densovirus that weakens the sea star’s ability to defend itself against microorganisms. This discovery, along with sightings of sea star hatchlings in the impacted areas, offer hope for the future of the species.
