Species Characteristics

Carmine Shiners, previously know as Rosyface Shiners, have a slender body and are moderately compressed laterally. Their mouth is large, terminal, and oblique with no barbel. The slender, slightly hooked pharyngeal teeth are arranged in a 2, 4-4, 2 pattern. A slightly de-curved, complete lateral line has 33 to 39 scales. Dorsal and pelvic fins have 8 rays, but the anal varies from 9 to 11 rays, and the pectorals have 12 to 18 rays. The dorsal fin is behind the insertion of the pelvic fins. The back is dark olive and may have a faint mid-dorsal stripe. Sides are silvery with a narrow emerald-lavender lateral band above the midline, and the belly is white. The base of the dorsal fin has a pink shade. Spawning males have a flush of pink or orange on the head and body, which gives rise to their common name.
