At Louisiana's Grand Isle East State Park, a former National Wildlife Federation employee captured video of a dolphin struggling to swim in water that had been tainted by the BP Deepwater Horizon oil spill.
In a blog post, Denise Ryan, who shot the video, said the dolphin kept moving back and forth around the pier until it finally disappeared. Ryan said she could see "tiny bits of dispersant in the water along with tiny gobs of oil."
