生物学特性     字汇 (例如 epibenthic)

Common in coastal and lagoon areas with mangroves (Ref. 9279). Also found in bays and harbors (Ref. 36575). Penetrate fresh water (Ref. 9279). Adults occur in small schools. Feed mainly on small fishes (Ref. 9279). Oviparous, with neustonic larvae (Ref. 36575). Eggs are attached to vegetation and floating objects via long filaments (Ref. 36575). Usually caught with the help of artificial lights (Ref. 9279). Marketed fresh (Ref. 9279).

常见于海岸的与具有红树林的泻湖区.(参考文献 9279) 也发现于海湾与港湾。 (参考文献 36575) 深入淡水。 (参考文献 9279) 成鱼形成小群鱼群。 主要捕食小鱼。 (参考文献 9279) 卵生的, 与漂浮性的仔鱼.(参考文献 36575) 卵经由长的丝状突起被依附于植物与漂浮目标。 (参考文献 36575) 通常用人造光的帮忙捕获了。 (参考文献 9279) 在市场上销售生鲜地了。 (参考文献 9279)
