marien bathydemersaal; standvastig; diepte 200 - 720 m (Ref. 1371), usually 350 - 550 m (Ref. 1371). Deep-water; 34°N - 24°N, 125°E - 140°E (Ref. 1371)

Maturity: Lm ? range ? - ? cm
Max length : 31.0 cm TL mannelijk / geslacht onbekend; (Ref. 1371)
Dorsale stekels (totaal) : 2; Anale stekels: 0. Snout short, conical; eyes large, its diameter greater than snout length. Scales medium-sized, uniformly covered with broad, short, triangular spinules in widely divergent V rows or irregularly quincunx order. Snout with a black margin along its leading edge; first dorsal fin uniformly dusky or darker proximally, but lacking a distinct black blotch.
Most common in about 350 to 550 m where water temperatures range from 6° to 12°C. Feeds primarily on euphausiids, prawns, and isopods. Spawning probably takes place in early spring.
