Gulf killifish (Fundulus grandis) embryos exposed to sediments from oiled locations in the Gulf of Mexico in 2010 and 2011 show developmental abnormalities, including heart defects, delayed hatching and reduced hatching success. Researchers discovered that crude oil toxicity continued to sicken the killifish for at least more than a year after the Deepwater Horizon oil spill in the Gulf.
