| Softshell Clam |
Softshell clams occur in almost all of Oregon’s estuaries and their range can extend very high into the estuary. In Coos Bay, for example they are found commonly in places as far as 30 miles from the ocean inlet.
Softshell clams are native to the East coast, where they are an important commercial fishery. They are believed to have been introduced to Oregon in the late 1800s, timed with the attempt to begin a fishery for the eastern oyster (Crassostrea virginica).

Erosion and softshell clams
When tidal channels re-route, softshell clams are often affected. Softshell clams live very high in the intertidal areas and the density of beds becomes obvious when these changes take place. |
