Checkered Madtom

Like many other madtoms, the checkered madtom has a stout body. The body is yellow and has four obvious saddle-like stripes of black on top. The bottom is white to yellow. The dorsal fin on the back has a black blotch on the top third of the fin. The caudal (tail) fin has a black bar at its base and at the end. The caudal fin is usually straight or slightly rounded. The checkered madtom is thought to be the second largest species of madtom commonly 4-7 inches, with the largest being Noturus flavus.

The checkered madtom is uncommon in the upper White River system in southern Missouri and northern Arkansas. The checkered madtom has a disjunct population in the Jacks Fork and Current River (Missouri) in Missouri. The fish inhabits the margins of pools and in the backwaters of clear small or medium rivers, usually with a moderate to high gradient. It is often found among leaves and woody debris. The fish is demersal—it stays near the bed of the body of water.
