Ecología
marino; agua dulce; salobre demersal. Subtropical; 35°N - 33°S, 99°W - 34°W
Western Atlantic: South Carolina to western Florida, USA (Ref. 26938) and the entire Gulf of Mexico to Brazil; absent from Bahamas and smaller islands in West Indies.
Length at first maturity / Tamaño / Peso / Age
Maturity: Lm 22.0, range 18 - ? cm
Max length : 40.0 cm TL macho / no sexado; (Ref. 3722); common length : 30.0 cm TL macho / no sexado; (Ref. 3722); peso máximo publicado: 1.0 kg (Ref. 4699)
Inhabits shallow coastal waters and common in brackish waters (Ref. 36880), mostly over mud bottoms in mangrove-lined creeks and lagoons (Ref. 3722); often entering a considerable distance into freshwaters (Ref. 36880). Feeds on aquatic insects, crustaceans, micro-bivalves and detritus (Ref. 36880). Marketed fresh; processed into fishmeal (Ref. 3722).
