Biologie     Glossaire (ex. epibenthic)

A common inshore and offshore shark found on the continental and insular shelves (Ref. 13567). Probably feeds on small fishes, cephalopods, and crustaceans (Ref. 244). Viviparous (Ref. 50449). Caught irregularly by inshore gillnet fisheries and occasionally by small-scale longlining (Ref.58048). Probably taken by artisanal fisheries wherever it occurs (Ref. 13567). Utilized fresh for human consumption and by-products processed into fishmeal (Ref. 244).

Viviparous (with a yolk-sac placenta), with 4 young in a litter (Ref. 244). Size at birth at least 20 cm (Ref. 244). Distinct pairing with embrace (Ref. 205).
