Freshwater Mussels

Most freshwater mussels live in runs and riffles on beds of cobble, gravel, sand, and silt, their existence dependent on water quality. But mussels themselves make a contribution to the water's purity with their method of filter-feeding. Adults spend their lives straining out silt, one-cell algae, microscopic animals, and debris. The combined work of entire beds of mussels can be significant downstream.
