Max length : 90.0 cm SL جنس نر / بدون خواص جنسي; (Ref. 1602); بيشينه وزن گزارش شده: 8.6 kg (Ref. 5450)
خارهاي باله پشتي (کل) : 0; شعاع نرم باله پشتي (کل) : 15 - 19; خارهاي باله مخرجي: 0; شعاع نرم باله مخرجي: 8 - 9. Tip of lower jaw broadly rounded; a spot of black pigment often present on the underside of snout, at least in smaller individuals; tooth patches on parasphenoid and basibranchial bones more broadly oval in shape, average width/length 0.38 and 0.45, respectively; number of teeth in pharyngobranchial tooth patch usually 5-15 (Ref. 9828). Compared to A. argentea which has a yellow spot on the axil of the pectoral fin, in this species, there is none (Ref. 74924).
Body shape (shape guide): fusiform / normal.
Inhabits mud flats of turbid inner reefs and mangroves and sandy lagoons (Ref. 9710). Benthopelagic in shallow, coastal areas (Ref. 58302). Grabs food from the substratum using its snout. Feeds on invertebrates, benthic species, mollusks and small crustaceans (Ref. 89972). Can tolerate oxygen poor water by inhaling air into a lung-like air bladder (Ref. 9710). Migrates to mass spawn at seaward mouths of channels on lunar cycle (Ref. 9710). Sold fresh in markets but seldom used for human consumption.
