Dorsal spines (total): 9 - 11; Dorsal soft rays (total): 25-28; Anal spines: 2; Anal soft rays: 10 - 11. Body silvery, dark grey on back with bluish reflections and numerous round black spots irregularly scattered on upper half, extending to dorsal and caudal fin. Spinous dorsal fin dusky, other fins pale to yellowish. Mouth large, oblique lower jaw projecting. Upper jaw with a pair of large canine-like teeth at tip. Lower jaw with an enlarged inner row of teeth, uniform in size and closely set. Chin without barbels or pores. Snout with 2 marginal pores.
