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.
