Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 45.0 cm TL male/unsexed; (Ref. 3132); max. published weight: 800.00 g (Ref. 3132)
soft rays: 20 - 22. Silvery, with faint dark horizontal lines between scale rows. Brown band from top of head through eye to chest (fading with growth). Another, less distinct, curved dark bands from nape across operculum and pectoral-fin base to belly. Median fins dusky or pale with dark margins. Body orbicular and strongly compressed, its depth more than twice head length and 1.2 to 1.4 times in SL. Head length 3.1 to 3.6 times in SL. Head profile of adults with a slight bump between eyes. Snout, preopercle flange, and lower jaw naked, rest of head scaly. Jaws with 2 to 4 rows flattened, tricuspid teeth. Small patch of teeth on vomer. Palatines toothless. Five pores on each side of lower jaw. Preopercle with a few rudimentary serrae along its rounded angle. Opercle with a flat spine, and a rounded bone on its upper portion (Ref 43039).
Inhabits coastal reefs. Often occurs ion silt-sand bottoms of coastal trawling ground in 10-40 m (Ref. 90102).
