The life cycle of freshwater mussels is dependent upon host fish. In order to complete the reproductive process, the glochidia or mussel larvae must attach to the gills of specific host fish where they will metamorphose into free-living mussels. Mussels, being sedentary creatures, are incapable of moving to find a host so they have evolved different methods of attracting their host to increase their reproductive success. While some mussels simply release packets of gochidia, called conglutinates, which fish may mistake for food, others have modified mantles or other adaptations which will attract fish to them.
