Description
Size: 35-38 cm .

Color: Overall color is silvery, frequently with a diffuse vivid pattern of 5 to 8 narrow dark bars on the side, including one through the eye and across the cheek. Fins are mainly clear to yellowish, sometimes there is diffuse mottling or spotting on dorsal, caudal and anal fins. Often there is a narrow brown bar across the base of the pectoral fins. Some adults possess a few scattered blue spots or scribbling on the snout and cheek.

Eye diameter is relatively large, its diameter about equal to or slightly larger than preorbital and inter orbital width. Relatively ovoid body and pointed caudal lobes are distinct. Height 2-2.3 in young, 2.6-2.8 in length with caudal. In adults 2.4-2.5, 3-3.1 in length with caudal. head 2.8-3, 3.7-3.9 in length with caudal. Eye 2.8-3.2, slightly less than snout in young, 1.2-1.3 in snout in older specimens. Inter orbital space slightly convex anteriorly, more so and even somewhat keeled posteriorly, Where it is also narrow and equal to or somewhat more or less than eye. Mouth somewhat oblique. Lips thick, papillose, as well as chin.

Maxillary reaching to below nostrils. Bands of pointed slender curved teeth anteriorly in both jaws, with an outer row of caninoid teeth, continued laterally as a single row. In the anterior part of the row these teeth are more or less curved, sometimes very strong and real canines, sometimes less slender and more conical. Those in the sides of the jaw conical and stout. Four or five transverse rows of scales on preoperculum. The depth of the posterior and inferior naked preopercular limb about 1.5 in the scaly part. 13-14 scales between occiput and origin of dorsal. Dorsal spines slender, but pungent, the first more than half length of second, which is shorter than third. Third and fourth spines longest, equal to snout and half eye together, or equal to snout in large specimens. Following spines slightly shorter.
Soft dorsal rounded, the median rays longest and longer than longest spines. Anal spines stouter than dorsal ones, the first one more than half length of second, the third longest, longer than eye in small specimens, equal to eye or somewhat shorter in large specimens. Soft anal rounded and less deep than soft dorsal. Pectorals less than half length of snout shorter than head, in young ones almost as long as head. Ventrals, with the first ray produced, as long as pectorals or slightly shorter. Caudal forked, the lobes pointed. Least height of caudal peduncle 1.3-1.4 in its length.
