生物學特性     字彙 (例如 epibenthic)

Adults inhabit neritic waters, often near sandy beaches (Ref. 5217). A shoaling species, generally near the bottom (Ref. 27121). They feed on planktonic invertebrates, primarily copepods, but also on gastropod larvae, ostracods and pteropods (Ref. 3277). Spawning occurs well offshore year-round (Ref. 26938). Eggs are pelagic (Ref. 4233). A good food fish (Ref. 9626). Caught commercially and used mainly for bait.

棲息於淺海的水域, 時常在沙灘的附近.(參考文獻 5217) 一個淺灘種, 通常在底部的附近.(參考文獻 27121) 吃浮游性無脊椎動物, 主要地橈腳類的動物, 也捕食腹足動物仔魚,介形蟲與翼足目的軟體動物。 (參考文獻 3277) 一個好食用魚.(參考文獻 9626) 商業地捕捉而且主要地使用作為餌料生物。 產卵相當外海全年。 (參考文獻 26938)
