生態学
海 底生の漂泳性; 海洋回遊性 (Ref. 51243); 深さの範囲 100 - 975 m (Ref. 9302), usually 200 - 400 m (Ref. 6181). Subtropical; 55°N - 43°S, 180°W - 180°E (Ref. 6181)
Circumtropical and temperate seas of the world.

Maturity: Lm ? range ? - ? cm
Max length : 300 cm TL オス/雌雄の選別がない; (Ref. 5951); common length : 150 cm SL オス/雌雄の選別がない; (Ref. 6181); 最大公表体重: 63.5 kg (Ref. 4699)
背面の脊椎 (合計) : 13 - 15; 背鰭 (合計) : 15 - 18; 肛門の骨: 0; 臀鰭: 15 - 18; 脊つい: 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.
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).
