Description

The central stoneroller is a cyprinid of the family Cyprinidae (Leuciscidae) reaching about 22 cm. The brownish body has an inferior mouth with a hard, cartilage-like ridge on the lower lip, with which the fish scrapes algae and growth off stones; the very long gut, coiled around the swim bladder, helps digest this plant diet. The species is native to the fresh water of eastern and central North America and lives in clear, flowing streams and rivers with stony bottoms. In spring the male digs a gravel nest with its head and develops large breeding tubercles. Through its grazing on stones it plays an important role in the stream ecosystem.
