Univ. of California (Davis), Jun 3, 2015 (emphasis added): In August 2011, scientists at the UC Davis Bodega Marine Laboratory walked into their labs to a strange, disturbing sight: Thousands of purple sea urchins and other marine invertebrates were dead in their tanks, which are fed directly by seawater. [The] ocean washed up carcasses of red abalone, large sea stars, and football-sized, snail-like chitons… even more heavily impacted as a population were the millions of purple sea urchins and tiny sea stars that died along a 62-mile stretch of coast… “We might not have known urchins and six-armed sea stars were affected if lab-held animals hadn’t died right in front of us,” said the study’s lead author Laura Jurgens… “We’re expecting real ecological changes in how these tide pools operate”… this die-off was fast, wiping out these two species in as little as a few days. The die-off also occurred about two years before [observance of] sea star wasting syndrome…

Santa Cruz Sentinel, Jun 3, 2015: [It was] a grim scene, with dead red abalone, purple sea urchins and tiny sea stars rotting across the Northern California shoreline… the same carnage [took place] at the UC Davis Bodega Marine Lab… scientists tallied almost 100 percent mortality of purple sea urchins and six-armed sea stars throughout the 62-mile study area… Researchers found only 10 purple sea urchins in the area once home to millions…
