生物學特性     字彙 (例如 epibenthic)

Adults are primarily oceanic, pelagic schooling species rarely seen on reefs (Ref. 48635, 90102). They feed mainly on fishes (Ref. 5213). Generally marketed fresh (Ref. 5284).

主要大洋性的 (參考文獻 48635), 住沿岸水域的接近水表面.(參考文獻 3197,11230) 形成魚群而且主要捕食魚。 (參考文獻 5213) 通常在市場上銷售生鮮地了。 (參考文獻 5284)
