背棘 (總數) : 0; 臀棘: 0; 臀鰭軟條: 12 - 15. Scutes present along back (before dorsal fin) as well as along belly. Upper jaw with median notch. Gill rakers fine and slender, about 130 to 150 in lower limb.

鱗甲存在的沿著背面 (在背鰭之前) 以及沿著腹面。 上頜有中央的凹槽。 鰓耙細而細長的, 大約 130 到 150 在下肢中。 臀鰭短,在最後的背鰭鰭條正後方。 鱗片有櫛狀結構後部的邊緣。 一個深色斑點在後鰓蓋並且向上到 4個數列垂直橢圓形的斑點沿著側面。
Occurs in coastal waters, forming large schools. Feeds by filtering phytoplankton (diatoms) and zooplankton (especially copepods), but will also take small fishes and crustaceans. Breeds in spring (Chile), depositing its eggs in coastal waters on sand, to which the sticky eggs cling, the larvae rising and joining the surface plankton on hatching. Marketed fresh, frozen, or canned.
出現於沿岸水域, 形成大群魚群。 濾食浮游植物 (矽藻) 與浮游動物 (尤其橈腳類的動物), 但是也吃小魚與甲殼動物。 繁殖於被在沿岸水域的砂上產卵的春天 (智利), 黏黏的卵黏附在上面, 仔魚升起而且結合表面浮游生物孵化時。 在市場上銷售生鮮地了, 冷凍, 或罐裝的。
