Vomer small, without posterior process; periphery of glossohyal bone with single row of blunt teeth, a few teeth located irregularly at center of distal region; base of adipose fin less than 20% of head length; eye small; adipose eyelid well developed (Ref. 33312). Distinguished by its midlateral scale count of 66 to 73 and the presence of 4 to 7 pyloric caeca (Ref. 27547). Lateral line short and incomplete, reaching about to tip of pectorals (Ref. 27547). Adipose sickle-shaped; pectorals small; pelvic fins originating behind or below dorsal origin (Ref. 6885). Light olive green to brownish on back, sides and belly silvery and iridescent with a bright reflecting band along the side in living specimens; males show more golden hues than females during spawning season (Ref. 6885). Branchiostegal rays: 7-8 (Ref. 35792). |
