Description:The sunflower sea star (Pycnopodia helianthoides) is a large sea star and fills the role of a keystone mesopredator. It is native to waters of the Pacific coast, from Alaska, through British Columbia and the West Coast of the U.S., and into northern Mexico. This species exhibits top-down predatory control of kelp predators in these regions. Prior to 2013, the global population of P. helianthoides was estimated to be in the billions. Since then, it is estimated that sea star wasting syndrome (SSWS), also called sea star wasting disease (SSWD), has eradicated over 90% of the population. In some areas these losses are estimated to be over 98%. The National Marine Fisheries Service (NMFS) Alaska Regional Office initiated a literature review on P. helianthoides with the NOAA Central Library in 2023. This bibliography is intended as a reference resource for staff within NMFS Alaska Regional Office, Protected Resources Division, who are conducting Endangered Species Act (ESA) Section 7 consultations that involve this, and other, species.
