Ecología
marino batipelágico; oceanodromo (Ref. 51243); rango de profundidad 150 - 3000 m (Ref. 3663), usually 300 - 400 m. Temperate; 81°N - 21°N, 82°W - 51°E

Longitud en la primera madurez / Tamaño / Peso / Edad
Madurez: Lm 15.0  range ? - ? cm
Max length : 55.5 cm TL macho / no sexado; (Ref. 106276); common length : 22.0 cm TL macho / no sexado; (Ref. 1371); peso máximo publicado: 830.00 g (Ref. 40637); edad máxima reportada: 20 años (Ref. 1371)
Espinas dorsales (total) : 0; Radios blandos dorsales (total) : 24 - 28; Radios blandos anales: 33 - 39. Dorsal fins widely spaced, interspace between second and third fins longer than base length of first dorsal fin. Lateral line continuous over whole body. Color is blue-gray dorsally, grading to white ventrally. Sometimes with a small black blotch at the base of the pectoral fin.
Body shape (shape guide): elongated; Cross section: circular.
Found over the continental slope and shelf to more than 1000 m, but more common at 300-400 m. Feeds mostly on small crustaceans but large individuals also prey on small fish and cephalopods. Makes daily vertical migrations: surface waters at night and near the bottom during the day. Sold fresh and frozen, and also processed as oil and fishmeal (Ref. 1371).
Oviparous and gonochorous (Ref. 205).
