Μήκος κατά την πρώτη ωρίμανση / Μέγεθος / Βάρος / Ηλικία
Γεννητική Ωρίμανση: Lm 54.3  range ? - ? cm
Max length : 110 cm TL αρσενικό/απροσδιόριστο; (Ref. 35388); μεγ. αναφερόμενη ηλικία: 25 έτη (Ref. 1371)
Ραχιαίες άκανθες (συνολικά) : 0; Εδρικές άκανθες: 0. Snout short, rather strongly pointed; mouth small, inferior. Underside of head almost entirely naked. Pyloric caeca about 19 or 20. Overall color is gray, darker ventrally on trunk; anal fin dark-edged, first dorsal and pectoral fins dusky (Ref. 1371). Front end of dorsal fin spine is serrated (Ref. 35388).
Body shape (shape guide): elongated; Cross section: circular.
Epibenthic, in deep waters down to 2740 (Ref. 58426). Adults are commonly found in about 300-500 m depth. Temperature preferences appear to range from about 1-4°C, although bottom temperatures below 0°C have been recorded at capture depths. Amphipods predominate in the diet, although polychaetes and various natant crustaceans are also important. Also feed on bivalves, isopods, echinoderms (notably ophiuroids), and ctenophores (Ref. 1371). Batch spawner (Ref. 51846).
