Length at first maturity / Size / Weight / Age
Maturity: Lm 20.0  range ? - ? cm
Max length : 46.0 cm SL male/unsexed; (Ref. 25); common length : 30.0 cm TL male/unsexed; (Ref. 3798); max. published weight: 900.00 g (Ref. 25); max. reported age: 4 years (Ref. 25)
(total): 12 - 13;
soft rays: 12 - 13. Back elevated; snout long and tapering. Mouth a little oblique; maxillary reaching vertical from first nostril. Scales in oblique rows above lateral line and horizontal rows below lateral line, extending on base of caudal, pelvic and pectoral fins; also forming a low sheath on base of anal and dorsal fins.
Inhabits coastal waters, over sand and mud bottoms. Forms schools. Mainly nocturnal and non-burrowing. Feeds on crustaceans and smaller fishes. Undergoes seasonal migration as well as local nocturnal-diurnal foraging migrations (Ref. 25).
Spawning may occur in open water just prior to inshore migration or in quiet inshore waters, such as harbors, estuaries, and inshore banks, but may begin on outer shores first. Pigfish spawn at dusk exclusively. In general, larger fish spawn first, with smaller ones spawning latest in the season.
