Maturity: Lm 44.8, range 50 - 63.5 cm
Max length : 69.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 40637); common length : 50.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 3265); 最大体重: 4.4 kg (Ref. 40637)
臀鳍软条: 22 - 28. Maxillary barbels, first ray of dorsal fin, and first ray of pectoral fin extended as long, flat filaments. 1 pair of barbels on chin.
上颌骨触须, 第一个背鳍的鳍条, 与第一个胸鳍的鳍条延伸如长又平坦的丝状突起。 1对触须在下巴上。
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)
