This species is endemic to Alabama in the United States. Its natural habitat is the Coosa River.^[2] Although the IUCN officially categorises the species as Data Deficient, it also considers it as Possibly extinct as it has not been recorded since the river was impounded.^[1] This latter classification is also supported by The Nature Conservancy.^[2] The common name is based on a river called the Hidden River.^{[citation needed]}
