Occurs on or near the bottom of the upper continental slope at 298-850 m; viviparous with yolk-sac dependency; no reproductive and diet data are available, however, it is presumed that the species feeds on small fishes, cephalopods, and crustaceans (Ref. 58048). Trawled mainly in 300-400 m (Ref. 58443). Marketed for its meat, fins, and liver oil which is of high value (Ref. 58048).
