FWS Digital Media Library — The U.S. Fish and Wildlife Service’s National Digital Library is a searchable collection of selected images, historical artifacts, audio clips, publications, and video. The fanshell is a species of aquatic bivalve mollusk in the family Unionidae. This clam is native to the United States, where breeding populations remain in only three rivers. It is a federally listed endangered species of the United States. All Unionidae are known to use the gills, fins, or skin of a host fish for nutrients during the larval glochidia stage. Cyprogenia stegaria release into the water a conglutinate mimicking an Oligochaeta worm which contains the mussel’s young. When a fish bites into the conglutinate lure, the young glochida are released and latch onto the fish’s gills for nutrients
