No horn-like projection on snout; Two bony plates on caudal peduncle, the keel rounded to angular (not pointed); Dorsal and ventral profiles of head equally convex; Interorbital broad, nearly flat; First dorsal spine longest and strongest; Caudal fin slightly emarginate, higher than body depth. Max. length: 60.0 cm SL. Depth range: 6 - 70 m, usually: 20 - 50 m.

Bluish grey body color, sometimes displays large whitish patch on side in area around pectoral fin; Has numerous black close-set spots on the upper half of its body and tail, and is white ventrally. Males assumes dark anterior body during courtship displays.
