Over the next two years, as geographically diverse populations continued to crash, scientists coined the term sea star wasting disease (SSWD) to refer to the unexplained forces that were causing the devastation.

It then rapidly began to lay waste to many as 20 different sea star … The absence of sea stars can enable other organisms that sea stars eat, like mussels, to multiply and drive out other nearshore inhabitants. Next week, I will post about sea star wasting syndrome, a devastating disease that has killed millions of sea stars in the last few years from California to Alaska. Sea stars with SSWS develop white lesions in the ectoderm quickly followed by decay of tissue surrounding the lesions which leads to fragmentation of the body and death. Now scientists believe that it may be respiratory distress. Some of these species stand at the brink of extinction. As many as 20 sea star species have been affected.

A mysterious wasting disease has been devastating sea star populations around the world for several years. As some sea star populations make a comeback, scientists may have found cause of ‘wasting disease’ By.
