Wavy-Rayed Lampmussel (Lampsilis fasciola)

The wavy-rayed lampmussel is a medium-sized freshwater mussel that lives mainly in gravelly riffle areas of streams and rivers. It is distinguished from other mussels by its yellow, rounded shell with numerous thin, wavy, green rays. The female of this species is unique in that it has evolved a minnow-shaped "lure" that it uses to attract its host fish, the smallmouth bass. Clear water may be a critical requirement for successful reproduction, and this could explain why the species appears to be disappearing from the murky waters of the Sydenham River.
