背棘 (总数) : 13 - 15; 背的软条 (总数) : 15 - 18; 臀棘: 0; 臀鳍软条: 15 - 18; 脊椎骨: 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.
皮肤非常粗糙的, 鳞片点缀着刺状的多骨小瘤了。腹面中央 (腹部的) 在腹的轮廓上的龙骨脊。身体是全身褐色的到深褐色的, 胸鳍与腹鳍黑色的顶端 , 第二个背鳍与臀鳍白色的边缘当幼鱼时标本。

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).
