生態学
海 底生の漂泳性; 深さの範囲 200 - 1200 m (Ref. 6181). Deep-water; 70°N - 47°S, 180°W - 180°E
Probably distributed worldwide in tropical and subtropical seas except in eastern Pacific and northern Indian oceans. Large-sized individuals stray in cold-temperate waters off Iceland, Norway, northern Japan and southern New Zealand (Ref. 6181). Reported from 19°41'S, 79°11'W (Ref. 11892).
サイズ / 重さ / 年齢
Maturity: Lm ? range ? - ? cm
Max length : 130 cm SL オス/雌雄の選別がない; (Ref. 6181); common length : 80.0 cm SL オス/雌雄の選別がない; (Ref. 6181)
背面の脊椎 (合計) : 20 - 22; 背鰭 (合計) : 19 - 24; 肛門の骨: 2; 臀鰭: 18 - 21; 脊つい: 34 - 36. Body fairly elongate and strongly compressed. Mouth with fang-like teeth. The tips of both jaws with dermal processes. Gill rakers degenerated. Color is dark brown with violet tint; fin membranes black; margin of anus black (Ref. 6181).
Adults, benthopelagic to mesopelagic, dwell on the continental slope or underwater rises, migrating to midwater at night (Ref. 6181). Eggs are pelagic (Ref. 6766). Larvae and juveniles, epipelagic to mesopelagic, are rather common in oceanic ichthyoplankton and are only found in the tropics (Ref. 6181). Feed on squid, fish and crustaceans (Ref. 6181). Consumed as food (Ref. 4537).
