Management Plan for the Rocky Mountain Ridged Mussel (Gonidea angulata) in British Columbia

The Rocky Mountain Ridged Mussel is a freshwater mollusc and was listed as a species of special concern under the Species at Risk Act (SARA), in July 2005. This large freshwater bivalve has a trapezoidal shell. The most distinctive feature of the shell is a prominent posterior ridge running almost parallel with the anterior margin, from the umbo to the angular basal posterior margin of each valve. The posterior length of the shell exceeds the anterior length of the shell.
