“In August 2011, scientists did a comprehensive examination of a 16-year-old male bottlenose dolphin. This dolphin — dubbed Y12 for research purposes — was found near Grand Isle, a Louisiana barrier island that was hit hard during the Gulf oil disaster.
Like many of the 31 other dolphins examined in a recent study, Y12 was found to be severely ill: underweight, anemic and with signs of liver and lung disease. The dolphins’ symptoms were consistent with those seen in other mammals exposed to oil; researchers feared many of the dolphins studied were so ill they would not survive.
Seven months later, Y12’s emaciated carcass washed up on the beach at Grand Isle.
More than 650 dolphins have been found stranded in the oil spill area since the Gulf oil disaster began. This is more than four times the historical average.”
