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.
