Using Molecular Tools to Recalibrate Freshwater Mussel Taxonomy with a Focus on Imperiled Species

Freshwater mussels of the family Unionidae, also known as naiads, pearly mussels, freshwater clams, or unionids, are a diverse group of bivalve mollusks that are distributed on every continent except Antarctica. Approximately 300 species are known from the United States, with most of this diversity residing in rivers of the Southeast where many endemic taxa have evolved.
