A tuberculate male and a female Central Stoneroller (Campostoma anomalum). Caught in dipnet from a tiny stream (less than 5 feet across, 6 inches deep). Kendall County, IL. (I assume they are both Centrals, but I do not know if Laregscale Stonerollers also occur here, so the female could conceivably be of that species instead.) April 15, 2016.
