and Wildlife Service, TVA, Tennessee Wildlife Resource Agency, and other law enforcement agencies are utilizing legislation and regulations to protect the snail darter during the recovery effort. It is recommended that at least five separate viable populations should be maintained, the species should be kept on the Federal List of Endangered and Threatened Wildlife, and federal permits to collect the species should be required. As a result of the current recovery plan, the snail darter's federal listing was degraded from endangered species to vulnerable species. However, it is still considered threatened. Taxonomy The snail darter was first formally described in 1976 by the American ichthyologist David A. Etnier with the type locality given as the Little Tennessee River near mouth of Coytee Spring in Loudon County, Tennessee. The specific name refers to the settlement of Tanasi in Monroe County, Tennessee which was the capital of the Cherokee Nation until 1725 And which is the origin of the name Tennessee. It is placed in the subgenus Imostoma and appears to be closely related to the stargazing darter (Percina uranidea). References Percina Fish described in 1976 ESA threatened species
