Adults are coastal inhabitants found on soft bottoms (Ref. 44894), over sandy substrate (Ref. 12693). Juveniles are found in brackish mangrove estuaries, sometimes enter fresh water (Ref. 2847, 44894), lakes (Ref. 4323), tidal creeks (Ref. 44894) and lower freshwater reaches of rivers (Ref. 12915). Feed on small crustaceans, polychaetes and forams on sand or muddy-sand bottoms (Ref. 12915), worms and insect larvae (Ref. 12693). Length at first reproduction was reported to be around 12 cm SL, for a population in a South African estuary (D. Woodland, pers.comm. 07/13). Salted or made into fish sauce.

Life cycle and mating behavior Maturities | Reproduktion | Spawnings | Egg(s) | Fecundities | Larver

Juveniles enter estuaries and mangrove areas at 1 cm SL and stay until they reach maturity, at which stage they move out to sea (Ref. 36558).
