Asiatic Clam Corbicula leana

This small exotic was first established in the 1930s in the western U.S. and spread eastward. The first known occurrence along the Atlantic seaboard was on the Ocmulgee River; it is now abundant throughout the Altamaha River basin, in some areas numbering in the hundreds per square meter.

When severely crowded, Asiatic clams may interfere with native mussels by creating a "cobbled" substrate unsuitable for many other species.
