Biology
Very common in lagoons and estuaries; an extremely euryhaline species (from 0-66‰), but preferring areas close to the sea in estuaries and lagoons (Ref. 57400), often with muddy substrates (Ref. 81659). Inhabits shallow coastal waters, estuaries and brackish lagoons (Ref. 2683), including mangroves (Ref. 2683, 81659), creeks, estuaries, inundated mudflats (Ref. 81659) and freshwater rivers (Ref. 7399). Oviparous, eggs are pelagic and non-adhesive (Ref. 205). Maximum reported size 297 mm FL, but possibly up to 400 mm (Ref. 57400, 81659).
