James spinymussel (Pleurobema collina)
This freshwater mussel filter feeds plankton and prefers silt-free environments. Like other mussels, the females carry eggs in their gills where they are fertilized after males release sperm into the water. The larvae or glochidia are released from the gills but must attach to a fish host to survive. The glochidia drop off the fish once they have grown into juvenile mussels. Once on the bottom, they grow into adults.
