|Lewis' Pearly Mussel was
once distributed over a large area in the systems of the Cumberland and
the Tennessee Rivers.
This species is known from empty shells alone, except for a single specimen with preserved soft tissue.
The larvae of the vast majority (of all ?) of the freshwater mussels live as parasites in the gills of various river fishes. About the symbiotic relationships of the extinct species, however, almost always nothing is known at all.
