Species Characteristics

Has a terete body that is slightly compressed. The body is olive-green to straw on the back with silvery sides and white beneath. A dark lateral band is sharply outlined above with a light streak, but dim below.

Pigmentation on the inside of the mouth is absent, except for a few melanophores on the oral valve. Hooked pharyngeal teeth are arranged in a formula of 2, 4-4, 2, but there may be variations. The breast is naked below the pectoral fins. The slightly de-curved lateral line has 34 to 37 scales, and may be interrupted with fewer than 10 unpored scales. Dorsal and pelvic fins have 8 rays, while the pectoral fin has 12 to 14 rays, and the anal fin has 7 rays.
