Turgid-blossom Pearly Mussel
''Epioblasma turgidula'', the turgid blossom pearly mussel, turgid riffle shell, turgid-blossom naiad or turgid blossom, was a species of freshwater mussel, a mollusk in the family Unionidae. The US Fish and Wildlife Service declared the species extinct and delisted it from the Endangered Species Act in 2023.

Its natural habitat was riffles and shoals of medium rivers, which have now largely been destroyed by dam construction and dredging. Like most other mussels in the sensitive genus ''Epioblasma'', this species experienced severe declines during industrialization due to pollution, siltation and habitat destruction. The last known population was recorded in 1965 from the Duck River in Tennessee, near the town of Normandy.

Tan-blossom Pearly Mussel
The northern riffleshell (''Epioblasma torulosa rangiana''), is a subspecies of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels. This subspecies is endangered. This species was formerly found widely in the Ohio River basin, but now the population is fragmented into only three viable groups. This river mussel needs gravel river beds and swift-flowing, well-oxygenated water. The reduction in range seems to be principally due to damming and the consequential silting up of rivers below the dam and competition from zebra mussels. Distribution and conservation status This species lives in Ontario in Canada. It was classified as endangered by COSEWIC. The Canadian Species at Risk Act listed it in the List of Wildlife Species at Risk The List of Wildlife Species at Risk currently has more than 800 entries for Canadian wild life species considered vulnerable; including 363 classified as endangered species, —190 threatened species, � ...

Spectacle Case Pearly Mussel
''Cumberlandia monodonta'' (common name spectaclecase) is a freshwater mussel endemic to the United States. Currently, ''C. monodonta'' is listed as an endangered species by the U.S. Fish and Wildlife Service and the International Union for Conservation of Nature. ''Cumberlandia monodonta'' was first reported in a newspaper titled ''The Disseminator (New Harmony, Ind.)'' by Thomas Say in 1829 under the name ''Unio monodonta''. The spectaclecase was then reclassified into the genus ''Cumberlandia'' by A. E. Ortmann in 1912. ''Cumberlandia monodonta'' has experienced a drastic decline in population due to human activity, resulting in its listing as "Endangered" by the Endangered Species Act and the IUCN. In particular, the construction of dams has caused significant problems that disrupt ''C. monodonta'''s habitat and food supply. The Endangered Species Act classifies ''C. monodonta'' as a highly threatened species with a low potential for recovery. Description Physical chara ...
