Central Stoneroller (Campostoma anomalum)

Description: 

The Central Stoneroller is widespread from the Great Plains to the Atlantic Coast drainages in northeastern North America. In the Tennessee and Cumberland river drainages, it is restricted to above Cumberland Falls and the Blue Ridge physiographic province. Central Stonerollers live in many different habitats of small creeks to medium rivers. They have a ridge made of cartilage on their lower jaw used to scrape algae off of rocks.
