Etymology: Bagre: Mozarabic, bagre, taken from Greek, pagros = a fish (Dentex sp.) (Ref. 45335). More on author: Mitchill.
Environment: milieu / climate zone / depth range / distribution range
; 海; 汽水性の 底生の; 深さの範囲 0 - 50 m (Ref. 5217). Subtropical; 43°N - 34°S, 98°W - 34°W
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.
Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm 33.0, range 50 - 63.5 cm
Max length : 69.0 cm TL オス/雌雄の選別がない; (Ref. 40637); common length : 50.0 cm TL オス/雌雄の選別がない; (Ref. 3265); 最大公表体重: 4.4 kg (Ref. 40637)
臀鰭: 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.
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.
