The Largescale Stoneroller is widespread from Alabama to Wisconsin. They 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.
