Ochre sea stars recovering
Update: 2025-12-08
Description
There has much coverage of the plight of sunflower sea stars, the large starfishes with 16 to 24 arms that inhabit the Pacific Coast of North America. A wasting disease that hit the population starting in 2013 killed off more than 90% of the population from Mexico to Alaska. Only recently has the underlying cause of the disease been identified: a specific bacterium of the Vibrio genus. But sunflower sea stars aren’t the only species that have fallen victim to the wasting disease. In fact, it has killed billions of sea stars in up to 20 species.
