Cumberlandia monodonta (common name spectaclecase) is a freshwater mussel endemic to the United States.[4] Currently, C. monodonta is listed as an endangered species by the U.S. Fish and Wildlife Service[2] and the International Union for Conservation of Nature.[1][5]
Cumberlandia monodonta was first reported in a newspaper titled The Disseminator (New Harmony, Ind.) by Thomas Say in 1829 under the name Unio monodonta.[6][7] The spectaclecase was then reclassified into the genus Cumberlandia by A. E. Ortmann in 1912.[8]
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.[4] The Endangered Species Act classifies C. monodonta as a highly threatened (endangered) species with a low potential for recovery.[4]
