The Brindled Madtom is found in central North America from Louisiana to Ontario, including the Tennessee and Cumberland river drainages. They live over gravel and sandy substrates with woody debris in creeks to small rivers. The common name refers to their dark mottled coloration with saddles across their back. 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, Brindled Madtoms are smaller catfish reaching a maximum size of five inches.
