Entorno: milieu / zona climática / rango de profundidad / gama de distribución
Ecología
marino bentopelágico; rango de profundidad 50 - 1000 m (Ref. 9784). Deep-water; 42°N - 38°S, 180°W - 180°E

Longitud en la primera madurez / Tamaño / Peso / Edad
Madurez: Lm ?, range 16 - ? cm
Max length : 33.0 cm SL macho / no sexado; (Ref. 9784); common length : 20.0 cm SL macho / no sexado; (Ref. 6181)
Espinas dorsales (total) : 30 - 36; Radios blandos dorsales (total) : 35 - 44; Espinas anales: 2; Radios blandos anales: 28 - 35; Vértebra: 57 - 64. Body is extremely elongate and compressed. Lower jaw extends anterior to upper jaw with a small conical dermal process. Upper jaw with 3 immovable and 3 or 4 movable fang-like teeth anteriorly. Lateral line situated closer to the ventral profile than the dorsal profile posteriorly. Color is silvery with narrow dark dotted lines along the body; the gill membranes are jet-black.
Body shape (shape guide): elongated; Cross section: compressed.
Oceanic, migrating upward at night to 100 to 200 m (Ref. 6181). Probably forming schools during daytime (Ref. 6181). Feed on crustaceans and small fish (Ref. 6181). Females mature at about 16 cm (Ref. 36731). Eggs and larvae are pelagic (Ref. 6766).
