Ecología
marino bentopelágico; oceanodromo (Ref. 51243); rango de profundidad 100 - 975 m (Ref. 9302), usually 200 - 400 m (Ref. 6181). Subtropical; 55°N - 43°S, 180°W - 180°E (Ref. 6181)
Circumtropical and Circumtemperate

Madurez: Lm ?  range ? - ? cm
Max length : 300 cm TL macho / no sexado; (Ref. 5951); common length : 150 cm SL macho / no sexado; (Ref. 6181); peso máximo publicado: 63.5 kg (Ref. 4699)
Espinas dorsales (total) : 13 - 15; Radios blandos dorsales (total) : 15 - 18; Espinas anales: 0; Radios blandos anales: 15 - 18; Vértebra: 32. Skin very rough, scales interspersed with spinous bony tubercles. Mid-ventral (abdominal) keel on the ventral contour. Body is uniformly brown to dark brown, tips of the pectoral and pelvic fins black, margins of the second dorsal and anal fins white in young specimens.
Body shape (shape guide): elongated; Cross section: compressed.
Usually over the continental shelf, sometimes in oceanic waters down to 800 m (Ref. 9302). Usually solitary or in pairs near the bottom (Ref. 6181). Migrates far offshore (Ref. 26139). Pelagic (Ref. 5951). Feeds on fish, crustaceans and squid (Ref. 6181). The peculiar wooden 'palu' or Ruvettus hook is used to catch this species in south central Pacific (Ref. 6181). The flesh is very oily, with purgative properties, if eaten much (Ref. 6181). Marketed fresh and as fish cakes in Japan (Ref. 9302); also processed into fishmeal (Ref. 5217). Maximum length reported to reach up to 2 m only (Heemstra, pers. comm. 03/03).
