Did you know?
The particular fish species which serves as the host for the parasitic glochidia (larvae) is unknown (Stryaer and Jirka 1997).

State Ranking Justification [-]
This species has declined over most of its range, nevertheless it is still relatively common and reproducing in the Susquehanna River basin, lower Schoharie Creek, and in tributaries of the St. Lawrence River. Most of the Hudson River records are historical (Strayer and Jirka 1997), and the great majority of the records in the state are of marginal population viability.
