ITIS Reports — Noturus stanauli ITIS (the Integrated Taxonomic Information System) is a source for authoritative taxonomic information on plants, animals, fungi, and microbes of North America and the world. The pygmy madtom has an extremely limited distribution, appearing only in samples taken from the Duck River, in Humphreys and Hickman Counties, Tennessee; and from the Clinch River, Hancock County, Tennessee. These two locations are separated by about 600 river miles, though no current evidence indicates the entire historical range of the species. The pygmy madtom is a species of fish in the family Ictaluridae endemic to the United States, in only two known regions of Tennessee. Madtoms are the smallest members of the catfish family. Members of the genus Noturus can be distinguished by their small size, unusually long adipose fin, and rounded caudal fin. Most specimens have been collected over shallow, fine gravel shoals with moderate to swift flow, usually near the stream bank.
