Fish Iowa - Fish Species - Spottail Shiner

Characteristics

A large, prominent spot at the base of the caudal peduncle, which is the basis of its common name, helps to distinguish it from other large, pale, and silvery shiners. The color above is very pale olive, and the sides and belly are silvery. A sub-terminal mouth is nearly horizontal and no barbel is present. Flat, hooked pharyngeal teeth are supported on heavy arches and have a variable formula of 0, 4-4, 0 to 2, 4-4, 2. A complete lateral line has 36 to 39 scales. The dorsal fin, inserted directly over the pelvic fins, anal fin, and pelvic fins has 8 rays, while the pectoral fins have from 13 to 15 rays. Dorsal and anal fins are more deeply curved than other Notropis species.
