Blue whales, the largest creatures on Earth, are ingesting 10 million pieces of microplastic daily, scientists estimate.
With plastic waste rapidly accumulating in the world’s oceans, researchers sought to gauge how much is consumed by humpback, fin, and blue whales off the U.S. Pacific Coast. All three feed by gulping up mouthfuls of krill and other tiny creatures and then pushing the seawater out through a bristle-like filter called a baleen. In the process, they are prone to swallowing large amounts of plastic.
Scientists estimated the weight of plastic ingested by tracking the foraging behavior of 65 humpback whales, 29 fin whales, and 126 blue whales that were each tagged with a camera, microphone, and GPS device that had been suction-cupped to their back.
