Western Atlantic: coast of Gulf of Mexico, Cuba, western margin of the Caribbean, and the northern margin of South America. Sometimes in rivers and estuaries.
西大西洋: 墨西哥灣，古巴的海岸，加勒比海的西方邊緣與南美洲的北方邊緣。 有時在河川與河口內。
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 44.8, range 50 - 63.5 cm
Max length : 69.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 40637); common length : 50.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 3265); 最大體重: 4.4 kg (Ref. 40637)
臀鰭軟條: 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.
上頜骨觸鬚, 第一個背鰭的鰭條, 與第一個胸鰭的鰭條延伸如長又平坦的絲狀突起。 1對觸鬚在下巴上。
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.
主要海洋但是進入半鹹淡的河口鹽度相當高的地方.(參考文獻 5217) 主要吃小魚與無脊椎動物。 背部與胸鰭被具備有一個鋸齒狀的直立硬棘, 那是都有有毒的。 經常被釣客捕獲沿著橋，碼頭與狹小甬道。 肉被認為是好的; 在市場上銷售生鮮地.。 (參考文獻 5217) 最小深度報告取自參考文獻 57178.
