<>Semotilus corporalis can be distinguished by the possession of the following characters: large eye; large lateral scales (43-50); moderately compressed body; fairly long, rounded snout slightly overhanging large mouth; dorsal fin origin over or slightly behind pelvic-fin origin; 8 dorsal rays; 8 anal rays; adults have scales on backs and upper side darkly outlined; and young has black stripe along side, dark caudal spot. Olive to gold-brown above, dark stripe along back; bright silver side, sometimes with purple or blue sheen; black bar along back of gill cover. Breeding males have fairly large tubercles on head (Ref. 86798).
Inhabits gravel- and rubble-bottomed pools and runs of small to medium rivers, and also lake margins (Ref. 86798).
