Central Stoneroller (Campostoma anomalum)

Description: 

The Central Stoneroller is widespread from the Great Plains to Atlantic Slope drainages in northeastern North America. It is restricted to above Cumberland Falls in the Cumberland River Drainage and to the Blue Ridge physiographic province in the Tennessee River Drainage. 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. Breeding males have a pattern of tubercles, horny projections, on their head and body, which are used during courtship.
