The Mud Darter is a widespread species found in lowland Gulf drainages in Texas, Louisiana, and Mississippi north through the Mississippi Embayment to Wisconsin and Minnesota. They inhabit slow-flowing riffles over rocks and debris. Mud Darters have five to six dark vertical bars on the back of their body.
