[12] Scientists noticed a rapidly declining population of common starfish (Asterias rubens) occurring off the east coast of the United States. Dawsoni, Solaster. We regularly update our website with the latest reports, as well as the Sea Star Map. Disease outbreaks can have substantial impacts on wild populations, but the often patchy or anecdotal evidence of these impacts impedes our ability to understand outbreak dynamics. Sea star wasting disease demography and etiology in the brooding sea star Leptasterias spp. "Will the Sea Stars Ever Be Able to Recover? We didn’t find any sea stars at the south T-pier; however, we found eight ochre stars under the north T-pier and countless bat stars. As many as 20 sea star species have been affected. "Pacific Rocky Intertidal Monitoring: Trends and Synthesis." Note that data submitted to us may be used by our research group for analyses, as well as by others who submit data requests to us. in locations along the Northeast Coast of the US in recent years. We would like to increase the number of sites where long-term sea star data are collected, but in order to ensure data consistency, it is essential that a MARINe researcher is involved with initial site set-up and sampling. A side by side comparison of two photographs taken at near Croker Island in British Columbia. The disease also seems more prevalent in sheltered waters than in open seas with much wave movement. Researchers still can’t explain exactly what caused the massive die-off, though they think it could be linked to climate change, according to OPB. [12][14], In 1978 large numbers of the predatory starfish Heliaster kubiniji succumbed to a wasting disease in the Gulf of California. [9], There have been signs of some recovery of ochre sea star populations (Pisaster ochraceus), with higher numbers of juvenile sea stars in the intertidal than had been previously common, especially for northern sites along the Pacific coast. doi: 10.1371/journal.pone.0225248. The first photograph in the below series of a sea star with wasting syndrome was taking on June 27th, 2014 on Guemes Island, Washington. This catastrophic event that has decimated many species of starfish and begun to affect other tidepool animals. Please continue to submit observations after spending time diving or exploring the intertidal. The collected information will also be used to document recovery of both sea star populations and the community affected by way of the loss of sea stars. All of these symptoms are also associated with ordinary attributes of unhealthy stars and can arise when an individual is stranded too high in the intertidal zone (for example) and simply desiccates. 41 likes. 2019 Nov 21;14(11):e0225248. [5][4][22] However, the biomass and the function of ochre sea stars in their communities, such as being important predators of mussels, has remained lower than pre-disease levels. Sea Star Wasting Disease (SSWD) has caused widespread mass mortality of . doi: 10.1371/journal.pone.0225248. Thus, there is still much work to be done before this mysterious disease is fully understood. [6] In 2014 it was suggested that the disease is associated with a single-stranded DNA virus now known as the sea star-associated densovirus (SSaDV); however, sea star wasting disease is still not fully understood. This sea star shows signs of complete tissue deterioration, the most severe category of sea star wasting syndrome, and is likely dead or dying. Researchers suspected a virus was responsible for the disease because sea stars got sick in … We analyzed nearly two decades of data from a coordinated … This unprecedented phenomenon, known as sea star wasting disease … Current thinking is that there is likely a pathogen involved, but environmental factors may also play a role, and contributing factors might vary regionally. The massive loss of these organisms could cause significant ecological consequences in their biological communities. "Sea Star Wasting Disease has caused the largest epidemic in marine wildlife history"-Dr. Drew Harvell, Marine Ecologist, Cornell University and author, Ocean Outbreak: Confronting the Rising Tide of Marine Disease THE SEA STARS ARE MELTING by Mary Kay Neumann Sunflower sea stars (commonly called starfish) are dying off by the millions on the Pacific Coast from Sea Star Wasting Disease. Typically, lesions appear in the ectoderm followed by decay of tissue surrounding the lesions, which can lead to eventual fragmentation of the body and death. The disease — known as sea star wasting syndrome — begins as a small lesion, and eventually results in the loss of limbs and ultimate disintegration and death of the leggy animal. A new study has revealed no one cause of the sea star wasting disease, which hit populations of the keystone predator ochre sea star particularly hard in 2014 and 2015. The arms may continue to crawl around for a while after being shed. The disease, called “sea star wasting syndrome” (SSWS) has persisted at low levels in most areas, and continues to kill sea stars. Sea Star Wasting Disease or Syndrome. Web. The contents of the Sea star wasting syndrome page were merged into Sea star wasting disease on 25 February 2014. In late August, the disease had also been found stretching from Alaska to the border of Mexico. Long-term trends in Pisaster ochraceus numbers at our monitored sites can be viewed by location here or by using our Interactive Map & Graphing Tool. Jaffe N, et al. There had been a great increase in sea star numbers three years earlier, though in 2013 they were dying off. “Densovirus associated with sea-star wasting disease and mass mortality” initially suggested  a link between a densovirus (SSaDV) and sea star wasting syndrome (SSWS) but subsequent work revealed that an association between a viral pathogen and SSWS was unlikely in any species other than Pycnopodia helianthoides.
