Habitat and Ecology:

Continental and insular shelves, often reef associated, and adjacent waters. From surface to depths of 600-800m. Young occur among reefs in shallower  water, closer to the shore, moving into deeper water as they grow. Feeds on teleosts, rays and octopi. Viviparous 1-11 pups (usually 5-6) per litter after approx. 12 months gestation.

Fishery Status:

This species is not protected or subject to fishery regulations. It is caught in the hand line and longline fisheries. Generally only juveniles and sub-adults are caught in the 
artisanal fishery as adults pup in shallower waters and then return to the waters of the drop off or “bordaz”. 


Adults typically occur off the edge of the plateau whilst juveniles can be found closer inshore. Young and sub-adults can be seen quite regularly at the Victoria market.
