生物学特性     字汇 (例如 epibenthic)

Mainly marine but enters brackish estuaries with relatively high salinities (Ref. 5217). Opportunistic feeders over mud and sandy bottoms (Ref. 27549). Feeds mainly on small fishes and invertebrates. The dorsal and pectoral fins are equipped with a serrated erectile spine, both of which are venomous. Commonly caught by anglers along bridges, piers and catwalks. Flesh considered good; marketed fresh (Ref. 5217). Minimum depth reported taken from Ref. 57178.

主要海洋但是用相当高的盐度进入半咸淡的河口.(参考文献 5217) 主要吃小鱼与无脊椎动物。 背部与胸鳍被具备有一个锯齿状的直立硬棘, 那是都有有毒的。 经常被钓客捕获沿着桥,码头与狭小甬道。 肉被认为是好的; 在市场上销售生鲜地了。 (参考文献 5217)
