"Failed Barataria Dolphin Pregnancies Linked To BP Spill"
"Only two of 10 Barataria Bay bottlenose dolphins that were found to be pregnant in 2011, a year after the BP Deepwater Horizon explosion oiled the bay, had successful pregnancies. And the survival rate through July 2015 for adult dolphins that were given health assessments in the bay in 2011 is 10 percent lower than found in two studies of dolphins in un-oiled Sarasota Bay, Fla."
