An Asian clam, a fresh water creature, is usually less than 50 millimeters.
It tends to be small and light-colored, with a shell ornamented by distinct, concentric sulcations, anterior and posterior lateral teeth with numerous fine serrations. It resides in brackish to freshwater rivers, lakes, streams, canals and reservoirs. This creature lies on or is slightly buried in materials such as sand, silt, or gravel-bottomed places. It usually prefers running water with high oxygen levels and has no tolerance for polluted or near-freezing water.
