Pectoral fin rather short, 1 1/3-1 2/3 times into head length; extending nearly to dorsal fin insertion. Axillary scale of pelvic fin long and pointed, length equal to or greater than snout length. Longest ray of dorsal fin slightly shorter to slightly longer than head length. Caudal peduncle depressed. Dorsal finrays 11-12; anal finrays 10-12; pelvic finrays 9; pectoral finrays 14-15. Lateral line scales 41-52. Colour: leading edge of dorsal fin and upper leading edge of caudal fin with characteristic row of dark spots. Body with 8-10 dark spots along the lateral line.

Habitat: generally in depths less than 100 m (maximum of c. 225 m) on sand and mud bottom. Food: predatory on small fishes. Anchovy and red mullet (Mullus surmuletus) reported as food items (Fischer, 1973). Reproduction: larval stage has been figured (Okiyama, 1973). Spawning occurs in April-May off Japan (Okada, 1955).
