背棘 (總數) : 8 - 9; 背的軟條 (總數) : 17 - 18; 臀棘: 3; 臀鰭軟條: 20 - 21. Diagnosis: body deep and strongly compressed, its anterior profile very steep up to dorsal-fin origin, and strongly compressed; head small; snout short; mouth small, terminal, strongly protrusible, with fleshy lips; teeth slender and pointed, set in bands in upper jaw; roof of mouth toothless; dorsal fin deeply notched; 1st dorsal fin spine small, forward-pointing and visible only in young individuals; pectorals falcate, very long, their tips almost reaching to caudal-fin base; hind margin of caudal fin slightly rounded; pelvic fins thoracic; scales finely ctenoid, covering body, bases of dorsal and anal fins and head, except snout and preopercle; preopercular margin denticulate; lateral line strongly arched (Ref. 81287).
Coloration: silvery grey, darker on back, almost white on belly; sides with a series of 8 brown, more or less faded vertical bars, always more distinct in young individuals (Ref. 81287).
Neritic species (Ref. 7350). Essentially marine, often living in groups (Ref. 81287) over sandy and muddy bottoms (Ref. 2683), between 20 and 50 m depth, and entering coastal lagoons where sexual maturation begins (Ref. 81287). Feeds of fish eggs, benthic invertebrates and detritus (Ref. 28587).
