生物学特性     字汇 (例如 epibenthic)

Inhabits coastal waters (Ref. 2683). Semipelagic, remains near the bottom during the day and moves up to the open water at night (Ref. 5377, 57395). Occasionally enters lagoons and estuaries at start of sexual maturation (Ref. 57395). Occurs over sandy and muddy bottoms. Feeds on invertebrates and small fishes (Ref. 5535).

栖息于沿岸水域。 (参考文献 2683) 在底部的附近保持在白天期间而且向上移动到开放水域在晚上。 (参考文献 5377) 生活在沙泥底之上。 吃无脊椎动物与小鱼。 (参考文献 5535)
