Critically endangered (IUCN) and federally endangered oyster mussels (Epioblasma capsaeformis). These mussels and many others are in danger of extinction because of habitat loss due to impoundments and pollution. Pollution from coal mining in the Clinch River watershed is of special concern. The fine sedimentation that comes downstream from the mines is thought to impede mussel survival.

Critically endangered (IUCN) and federally endangered Cumberlandian combshell (Epioblasma brevidens). It has lures that look like fish eggs on top that are used to attract fish. When a fish strikes at the lures, the mussels then eject their larvae into the fish's gills and are able to increase their distribution, even upstream. The Clinch River has more federally listed aquatic species than any river in North America, yet is threatened by pollution and habitat loss. Coal mining in the watershed now raises the threat even more.

They have ball lures on top that are used to attract fish to come near. When a fish strikes at the lures, the freshwater mussels then eject their larvae into the fish's gills and are able to increase their distribution.

They are surrounded in the central box by catspaws, which are in rapid decline. The rest of the photo shows ten more Epioblasma species that are either extinct or nearly so.
