生態学
海 底生の漂泳性; 深さの範囲 0 - 400 m (Ref. 6181). Deep-water; 39°N - 44°S, 25°E - 134°W (Ref. 6181)

サイズ / 重さ / 年齢
Maturity: Lm ? range ? - ? cm
Max length : 200 cm TL オス/雌雄の選別がない; (Ref. 4408); common length : 100.0 cm SL オス/雌雄の選別がない; (Ref. 9784)
背面の脊椎 (合計): 17 - 19; 背鰭 (合計): 16-17; 肛門の骨 1; 臀鰭: 16 - 17; 脊つい: 34. Two lateral lines, originating above the upper angle of gill opening, branching below the 4th dorsal-fin spine or slightly behind it, upper line running along the first dorsal-fin base and ending below about the end of the first dorsal fin, lower line abruptly curved backward from bifurcation, running mid laterally to the base of the middle caudal-fin ray. Body color is dark brown with slightly metallic reflections, sometimes slightly paler on belly. Dorsal fin membranes with black markings.
Mesobenthopelagic, down to depths of 400 m or more, often at the surface at night around Okinawa, Japan (Ref. 6181). The largest populations are probably on the slope of seamounts or ridges (Ref. 6181). Feeds on a variety of mesopelagic fish, squid and crustaceans (Ref. 6181).
