The Yellowfin Madtom is a federally threatened species that is found in the upper Tennessee River Drainage in Georgia, Tennessee, and Virginia. They live in rocky pools of creeks to small rivers. As the common name suggests, Yellowfin Madtoms have yellow coloration in their fins. As members of the catfish family, all madtoms have whiskers (barbels) around their mouth with taste buds that aid in finding food. Like all members of the genus Noturus, Yellowfin Madtoms are smaller catfish reaching a maximum size of six inches.
