Previous work suggested that sea star-associated densovirus (SSaDV) was the best candidate pathogen responsible for sea star wasting disease (SSWD) among about two dozen species affected by it. Since then, sea star wasting events have been observed in 1982-83, 1997, and 2008. The sunflower sea star has been hit especially hard. Henricia spp. The disease leads to behavioral changes, lesions, loss of turgor, limb autotomy, and death characterized by rapid degradation ("melting"). So about two weeks ago I was in Seattle at the Sea Star Wasting Summit, hosted by the Seattle Aquarium! Involving citizen scientists to survey the nearshore subtidal for evidence of sea star wasting syndrome will greatly improve our understanding of the spatial extent of the syndrome and track changes through time. An epidemic wasting disease began in 2013, affecting sea stars Images of lesions and unnatural body twisting typical of sea star wasting disease. Dermasterias imbricata. Two of the most affected sea stars, the ochre and the sunflower stars, were once abundant on the British Columbia coast, but both were ravaged by sea star wasting disease, she said. Populations of at least 20 asteroid species on the Northeast Pacific Coast have recently experienced an extensive outbreak of sea-star (asteroid) wasting disease (SSWD). It has been called “sea star wasting syndrome” because some of the signs resemble those of conditions seen before on both North American coasts. “Numbers of the sea stars have stayed so low in the past three years, we consider them endangered in the southern part of their range, and we don’t have data for northern Alaska.” Since 2013, sea star wasting disease has brought about massive mortality in multiple sea star … A sea star is missing two limbs.

The wasting disease was first noticed in ochre sea stars along the coast of Washington in June, 2013. Sea Star Wasting Disease or Syndrome. The contents of the Sea star wasting syndrome page were merged into Sea star wasting disease on 25 February 2014. The epidemic spread from Alaska to Baja, California, and wiped out 80 to 99 percent of the ochre sea star population. The absence of sea stars can enable other organisms that sea stars eat, like mussels, to multiply and drive out other nearshore inhabitants. Sea star wasting resembles a mash-up of images from a horror movie. The disease that ... More than 80 percent of the ochre sea stars on the northern coast died as a result of that outbreak of sea star wasting syndrome, as the disease is called. Since 2013, wasting has been observed in 20 species of sea stars, and in other echinoderm species as well, including sea urchins. Warming seas closely related to die-off sea star Since 2013, about 20 sea star organisms between Mexico and Alaska have been destroyed by a sea star wasting disease. Disease is killing off sea star populations, reducing their numbers by more than 50 percent. Recently however, a severe disease outbreak occurred in a group of very well-studied organisms–sea stars along the west coast of North America. For the contribution history and old versions of the redirected page, please see its history ; for the discussion at that location, see its talk page .
