Environment: milieu / climate zone / depth range / distribution range
Marine; bathydemersal; depth range 140 - 650 m (Ref. 26346). Deep-water; 36°N - 40°S, 120°E - 173°W (Ref. 54331)

Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 92 - ? cm
Max length : 126 cm TL male/unsexed; (Ref. 6871)
Found on the uppermost continental and insular slopes, and probably the outer continental-insular shelves (Ref. 31367). Probably feeds on bottom fishes and some invertebrates (Ref. 247). Ovoviviparous (Ref. 205), with 10 pups in a litter (Ref. 247). Although not utilized commercially, the liver is relatively high in squalene oil (Ref. 6871).
