Rayed Bean (Villosa fabalis)

 

 

The rayed bean is a freshwater mussel that has been extirpated from Illinois, Kentucky, and Virginia but is still found in Indiana, Michigan, New York, Ohio, Pennsylvania, Tennessee, West Virginia and Ontario, Canada. It is a small mussel, usually less than 1.5 inches long. Generally, it lives in smaller, headwater creeks, but is sometimes found in large rivers and wave-washed areas of glacial lakes. The rayed bean prefers gravel or sand substrates, and is often found in and around roots of aquatic vegetation.

The rayed bean, a small mussel that only grows to about 1 1/2 inches in length, can no longer be found in much of its historic range in the Midwest and Eastern U.S.
