Report warns that 14 species are still struggling from the 2010 disaster.
Four years after the biggest oil spill in U.S. history, several species of wildlife in the Gulf of Mexico are still struggling to recover, according to a new report. In particular, bottlenose dolphins and sea turtles are dying in record numbers, and the evidence is stronger than ever that their demise is connected to the spill, according to Doug Inkley, senior scientist for the National Wildlife Federation, which issued the report.
—More than 900 bottlenose dolphins have been found dead or stranded in the oil spill area since April 2010. If you stretched the corpses lengthwise, that’s 1.5 miles (2.4 kilometers) of dead dolphins, Inkley said. Scientists know that is more than in previous years because they’ve been recording deaths and strandings in the Gulf for a decade.
—There are five species of sea turtle that live in the Gulf, and all of them are listed as threatened or endangered by the Endangered Species Act. About 500 dead sea turtles have been found in the spill region every year since 2011—”a dramatic increase over normal rates,” according to the NWF. What’s unknown is how many turtles died at sea and were never recovered by scientists.
—An oil chemical from the spill has been shown to cause irregular heartbeats in the embryos of bluefin and yellowfin tuna. That’s a critical stage of development for the fish, so there’s a lot of concern that the damage could cause heart attacks or deaths, Inkley said.
—Loons, birds that winter on the Louisiana coast, are carrying increasing concentrations of toxic oil compounds in their blood.
—Sperm whales that swam near the BP well have higher levels of DNA-damaging metals in their bodies than in the past. The metals in their bodies, such as chromium and nickel, are the same ones that were present in the well.
