Comments: Occurs on or near the bottom of upper continental and insular slopes.  Viviparous with yolk-sac dependency; gives birth to 4-16 pups, gestation unknown.  Feeds mainly on small fishes, cephalopods, and crustaceans.  Usually caught by demersal longline fisheries operating in deepwater.  Marketed for its meat, fins, and liver oil which has a high value (Ref. 58048).
