背棘 (總數) : 0; 背的軟條 (總數) : 9 - 11; 臀棘: 0; 臀鰭軟條: 12 - 17; 脊椎骨: 64 - 67. 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).

Individuals 3.5 cm may ascend rivers, presumably returning to the sea shortly after (Ref. 27547). Presumably young move offshore and reappear inshore as mature adults (Ref. 27547). At sea, they feed on small crustaceans, worms and jellyfish, as well as larval fishes (Ref. 6885, 10276). Females reach age 3, males age 2 (Ref. 27547). Oviparous, with demersal eggs and planktonic larvae (Ref. 35792). Eggs are laid on beaches with heavy surf action (Ref. 33312).

生命週期和交配行為 成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
Schools approach the beach to spawn, usually with the females appearing a few days before the males. At spawning, large numbers of males mill about near the edge of the surf. When a female is seen, numbers of males pursue her and try to get into spawning position. If she swims to deeper water, the males desert her. 1 to 5 males swim parallel to and slightly behind a ripe female. The males press against the female and as they reach water 2.5 to 5 cm deep, the fish bend and vibrate, releasing eggs and sperm, then retreat to deeper water. The spawning act may be repeated on several successive waves. Wave action buries the eggs, usually to a depth of 2.5 to10 cm but sometimes to as deep as 30 cm (Ref. 27547).東太平洋: 聲音威廉王子，阿拉斯加灣到長堤市，美國的南加州。 報告從西太平洋是 Hypomesus japonicus 的誤鑑。
