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).
棲息於沿岸水域。 (參考文獻 2683) 在底部的附近保持在白天期間而且向上移動到開放水域在晚上。 (參考文獻 5377) 生活在沙泥底之上。 吃無脊椎動物與小魚。 (參考文獻 5535)
