Environment: milieu / climate zone / depth range / distribution range
Ecologia
marino batidemersale; distribuzione batimetrica 80 - 1830 m (Ref. 50550). Deep-water; 57°N - 34°N, 130°E - 165°W (Ref. 1371)
North Pacific: central Japan to the Okhotsk to Aleutian Islands and Bering seas.
Length at first maturity / Size / Peso / Age
Maturity: Lm 43.8, range 40 - 47 cm
Max length : 72.0 cm TL maschio/sesso non determinato; (Ref. 56410); common length : 50.0 cm TL maschio/sesso non determinato; (Ref. 56527); peso massimo pubblicato: 1.5 kg (Ref. 56527); Età massima riportata: 26 anni (Ref. 56452)
Spine dorsali (totale) : 0; Spine anali: 0. Eyes relatively small, less than snout length in diameter. Chin barbel absent. Pectoral and pelvic fins reaching beyond level of anal fin origin.
Found in the continental slope (Ref. 1371). Many specimens taken from a whale stomach (Ref. 1371). Gut content of a 3.86 cm SL specimen contained a large number of grasping spines of arrow worms (Chaetognatha spp.), while a 4.01 cm SL specimen contained 6 individuals of the copepod Metridia pacifica (Ref. 87085).
