Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm ?, range 59 - ? cm
Max length : 84.0 cm TL オス/雌雄の選別がない; (Ref. 6871)
背面の脊椎 (合計) : 2; 肛門の骨: 0. Black in color, small dorsal fin spines, moderately long snout, small lanceolate teeth without cusplets in upper jaw and large high, knife-cusped cutting teeth in lower jaw, mouth moderately wide and nearly transverse, caudal fin with strong subterminal notch and short lower lobe (Ref. 247).
Demersal or pelagic near continental slopes and seamounts in depths of 550-2,000 m (Ref. 6871, 58302). Also found from the surface to 580 m over deep water (Ref. 26346). Ovoviviparous (Ref. 205). Used dried and salted for human consumption and for fishmeal (Ref. 6871). Caught rarely by longline fisheries operating in deepwater; also caught, but rarely landed, by pelagic tuna longline fisheries (Ref.58048).
