Plethobasus cicatricosus, the white warty-back pearly mussel or white wartyback, is a species of freshwater mussel in the family Unionidae, the river mussels. Once widely distributed in the Ohio, Cumberland, and Tennessee River systems in the United States, its range has declined dramatically to the point of near-extinction. It is a federally listed endangered species of the United States.

This mussel is yellow-green or yellow-brown in color. The nacre is white and partly iridescent. [2] There is a row of tubercles on one edge of the shell. [3]

The white wartyback lived in the main arteries of big rivers. [2] It was distributed through Alabama, Illinois, Indiana, Kentucky, Ohio, Tennessee, and West Virginia. It has now been extirpated from all of these states except for Tennessee and Alabama, where it possibly remains in the main flow of the Tennessee River. However, no live individuals have been documented since 1997. [4]

If a viable population is discovered, plans exist for the white wartyback to be reintroduced to the French Broad River and the Holston River in Tennessee. [3] There are currently no live individuals that exist in laboratories or propagation facilities. [4]

Tennessee River River in the southeastern United States

The Tennessee River is the largest tributary of the Ohio River. It is approximately 652 miles (1,049 km) long and is located in the southeastern United States in the Tennessee Valley. The river was once popularly known as the Cherokee River, among other names, as the Cherokee people had their homelands along its banks, especially in what are now East Tennessee and northern Alabama. In addition, its tributary the Little Tennessee River, flows into it from Western North Carolina and northeastern Georgia, where it also was bordered by numerous Cherokee towns. Its current name is derived from the Cherokee town, Tanasi, which was located on the Tennessee side of the Appalachian Mountains.

Freshwater drum Species of fish

The freshwater drum, Aplodinotus grunniens, is a fish endemic to North and Central America. It is the only species in the genus Aplodinotus, and is a member of the family Sciaenidae. It is the only North American member of the group that inhabits freshwater for its entire life. Its generic name, Aplodinotus, comes from Greek meaning "single back", and the specific epithet, grunniens, comes from a Latin word meaning "grunting". It is given to it because of the grunting noise that mature males make. This noise comes from a special set of muscles within the body cavity that vibrate against the swim bladder. The purpose of the grunting is unknown, but due to it being present in only mature males and during the spawning season, it is assumed to be linked to spawning.
