More on authors: Quoy & Gaimard.
Environment: milieu / climate zone / depth range / distribution range
Marine; freshwater; brackish; reef-associated; depth range 0 - 55 m (Ref. 26912). Subtropical; 43°N - 51°S, 98°W - 34°W
Western Atlantic: Massachusetts, USA and Bermuda to Argentina; including the Gulf of Mexico and the Caribbean Sea (Ref. 9626).
Length at first maturity / Size / Weight / Age
Maturity: Lm 11.0  range ? - ? cm
Max length : 25.5 cm TL male/unsexed; (Ref. 111768); common length : 15.0 cm TL male/unsexed; (Ref. 3722)
Inhabits shallow waters, being especially abundant over mud bottoms in mangrove-lined lagoons or creeks; larger individuals may also occur on vegetated sand grounds in marine areas. Enters fresh water in limestone regions (Ref. 7251). May occur in aggregations (Ref. 3722). Probably feeds on small benthic invertebrates (Ref. 3722). Marketed fresh but not highly esteemed (Ref. 3722).
