A common inshore and offshore species, demersal in intertidal habitats to depths of at east 220 m (Ref.58048). Found from the intertidal to the uppermost continental slope (Ref. 9862, 11230). A carnivore feeding on benthic animals. Ovoviviparous (Ref. 50449). Caught occasionally by inshore, demersal longline fisheries. Utilized for its meat and cartilage (Ref.58048).
Life cycle and mating behavior
Maturities | تولید مثل | Spawnings | Egg(s) | Fecundities | توزاد ( لارو)
