Environment / Climate / Range
Marine; bathypelagic; depth range 350 - 3000 m (Ref. 1371), usually 1300 - 2500 m (Ref. 5951). Deep-water; 62°N - 62°S, 180°W - 180°E
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 41 - 43 cm
Max length : 75.0 cm SL male/unsexed; (Ref. 5208)
Circumglobal: Except the North Pacific north of 10°N. Reported from the Walvis Ridge and near the Discovery and Meteor seamounts (Ref. 44938).
Found on the continental slope and upper rise (Ref. 6606). Epibenthic (Ref. 58426) and benthopelagic (Ref. 5951). Deep waters to 3277 m (Ref. 58426). May move offshore with age and spawn in the deep parts of its range. Off the eastern coast of United States, it is speculated that the population use the area only as feeding grounds with spawning taking place to the north. Feed on benthic invertebrates (Ref. 9319).
