Biologie     Glossaire (ex. epibenthic)

A fairly common species found on continental and insular slopes (Ref. 6871), on or near the bottom (Ref. 5578). Feeds mainly on fish and cephalopods (Ref. 6871). Ovoviviparous (Ref. 205), with 4-8 young in a litter (Ref. 6871), born at 28-35 cm (Ref. 26346). The flesh is high in mercury; utilized as fishmeal and source of squalene (Ref. 6871).
