Orca Spotted with Plastic Bag in Mouth Researchers snapped a picture of a baby killer whale in the Pacific Northwest holding a plastic bag in its mouth, just the latest example of plastic pollution in the world's oceans. Last month, scientists from the Center for Whale Research monitoring orcas in the Salish Sea say they spotted a calf playing with what at first looked like a small scrap of blubber. When the baby whale dropped the item from its mouth, they realized it was actually a plastic bag.
