Unfortunately, much of this diversity is now under threat. From coal power plants to everyday trash, the health of the Clinch is severely impacted from a number of pollutants. Freshwater mussels also have some pretty interesting behaviors. Here a female Oyster mussel (Epioblasma capsaeformis) has trapped a fish host using a modified lure.

With large congregations of females laying their eggs in the same area, giant mats of eggs can often be seen floating along the surface. These blobs of eggs will eventually develop into tadpoles and release from their gelatinous casings to explore their new wetland home.
