Reproduction

All Unionidae are known to use the gills, fins, or skin of a host fish for nutrients during the larval glochidia stage. Lampsilis cardium accomplishes this by having the inner sides of its mantle flaps marked with longitudinal stripes, resembling a small fish of the genus Notropis. When these are attacked and ruptured by a striking predator fish, especially Micropterus coosae, the mussel larva is released into the gills of the host fish where it feeds and develops.[2][3]
