Large plankton feeders such as whale sharks and manta rays swallow gallons of water at a time, plastic and all. Whether at the large, medium, small, or ultra-small scale, ingested plastic lumps, clumps, pellets, or microscopic mites kill by physically obstructing, choking, clogging, or otherwise stopping up the passage of food.”
