The Slender Madtom has a disjunct distribution in the central United States, including the Tennessee and Cumberland river drainages. They live in rocky pools and riffles of small creeks to small rivers. As the common name suggests, Slender Madtoms have a slender body. 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, Slender Madtoms are smaller catfish reaching a maximum size of 5.75 inches.
