    Habitat and Biology
    A large, sluggish bottom shark sometimes occurring in shallow water but primarily a deepwater species, occurring on the continental and insular shelves and upper slopesat depths from 18 to 900 m.
    Ovoviviparous, number of young per litter from 15 to 24; may breed in April in Indian waters.  Eats smaller sharks (spiny dogfish), bony fishes (including ling, catfish, and lizardfish), and crabs.
    Maximum total length about 3.1 m. Young born between 29 and 90 cm, adult females reported at 213 to 230 cm, adult males reported at 150 to 174 cm.
    Interest to Fisheries
    Apparently relatively common only in the eastern Atlantic, especially from the North Sea to Portugal, where it is caught in bottom trawls and on line gear.
    Utilized in the eastern Atlantic for fishmeal; liver oil has high value for medicinal purposes in South Africa.Relatively unimportant as a fisheries species.
