Body short, deep, and compressed; mouth small; teeth small, villiform, and only slightly hooked, didsappearing with age; lower branch of first gill arch with 9 to 12 gill rakers; dorsal fin with 6 spines followed by another spine and 17 to 19 soft rays (VII+I,17-19); nape prominent in adults; upper third of head and body dark; belly silvery; a dark axillary stain I covered by the pectoral fin (Ref. 55763).
Adults occur in coastal waters (Ref. 9283). They are common in shallow water and feed mainly on mollusks, but also take crustaceans and small fishes (Ref. 9283). Juveniles are frequently encountered in estuaries and feed on a variety of benthic invertebrates (Ref. 9283). Marketed fresh and salted or dried (Ref. 9283).
出現於沿岸水域。 (參考文獻 9283) 成魚是常見於淺水區而且主要捕食軟體動物, 也捕食甲殼動物與小魚.(參考文獻 9283) 稚魚時常在河口被見到並且吃多種底棲的無脊椎動物.(參考文獻 9283) 在市場上銷售生鮮地了與鹽醃或乾燥的.(參考文獻 9283)
