These sorts of results are not entirely new. Previous experiments on the effect of the 1989 Exxon Valdez oil spill that devastated Alaskas waters have yielded similar results. But that spill involved oil coating the shoreline, so the fish species that were affected were animals that physically deposit their eggs on or near the shoreline, Incardona says. So this latest experiment represents the first time that scientists have been able to demonstrate cardiovascular effects in pelagic fish — fish that hang out in the middle of the water column, instead of at the surface of the water or near the bottom.
