Freshwater mussels are filter feeders who burrow in the substrate of rivers, streams, and lakes throughout the world. The U.S. alone is home to some 300 species. According to the U.S. Fish and Wildlife Service (USFWS) and the Nature Conservancy, approximately 70 percent of mussel species in North America are extinct or endangered.
