Environment / Climate / Range
Marine; brackish; demersal; depth range 0 - 50 m (Ref. 5217). Subtropical; 43°N - 8°N
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 50 - 63.5 cm
Max length : 69.0 cm TL male/unsexed; (Ref. 40637); common length : 50.0 cm TL male/unsexed; (Ref. 3265); max. published weight: 4.4 kg (Ref. 40637)
soft rays: 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.
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.
Mainly marine but enters brackish estuaries with relatively high salinities (Ref. 5217). 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.
