freshwater clam
Lake-dwelling filter-feeder
Freshwater clams are bivalve mollusks that live in rivers, lakes, and streams rather than saltwater.
They filter water through their bodies, feeding on microscopic particles.
Many species produce pearls, though not of gem quality.
The shells were historically used for buttons.
The river bottom was thick with freshwater clams.
