Μέγεθος / Βάρος / Age
Maturity: Lm ? range ? - ? cm
Max length : 31.0 cm TL αρσενικό/απροσδιόριστο; (Ref. 1371)
Ραχιαίες άκανθες (συνολικά) : 2; Εδρικές άκανθες: 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.
