生態学
海 深海浮遊性; 深さの範囲 450 - 3000 m (Ref. 50550). Deep-water; 67°N - 60°S, 86°W - 122°W (Ref. 1371)
Spotty records from the subarctic and subantarctic to temperate waters of the Atlantic Ocean. South Atlantic: along the coast of Africa, on Walvis Ridge, near Discovery and Meteor seamounts and on the continental slope of Antarctica (Ref. 44938). Northwest Atlantic: Canada (Ref. 5951). North Pacific: northwestern Bering Sea and the Pacific Ocean south of the Gulf of Alaska to California and to Japan and the Sea of Okhotsk.

Max length : 56.0 cm TL オス/雌雄の選別がない; (Ref. 1371)
背面の脊椎 (合計) : 0; 背鰭 (合計) : 58 - 67; 肛門の骨: 0; 臀鰭: 42 - 53; 脊つい: 52 - 55. Eye large, its diameter about equal to snout length. Lower jaw slightly projecting; chin barbel absent. Elongate filament in first dorsal fin absent. Anal fin originating at about the midlength of body, deeply indented; pectoral fins not reaching to anal fin origin. Outer 2 pelvic rays elongate. Anterior gill rakers of 1st arch longer than gill filaments. Ventral light organ absent. Color is generally pale, silvery in fresh specimen; urobranchial cavity black (Refs. 1371, 43939).
Epibenthic (Ref. 58426). Food consists of free-living small animals, such as crustaceans and squids. This species is reportedly being caught by trawl in temperate waters of Australia (Ref. 9563).
