Widespread in southern Australia and throughout New Zealand, but uncommon and only occasionally caught. No information available on catches by commercial vessels, no directed fisheries, but likely to be taken as trawl bycatch. Biology poorly known but fecundity is low (probably 7 to 8 pups/litter).
|Range Description:||Australia (from Newcastle in New South Wales to the western Great Australian Bight) and New Zealand (throughout mainland New Zealand and Stewart Is-Snares Island Shelf; Chatham Rise and Chatham Islands; scattered records from Challenger Plateau and Campbell Plateau). Most New Zealand records from Chatham Rise. Depth range 45 to 650 m in Australia and 126 to 1,067 m in New Zealand. Most common at 300 to 600 m in New Zealand.|

|Habitat and Ecology:||
Habitat poorly known, but occasionally caught by bottom trawlers. Possibly also occurs over foul ground.
Little is known of the biology of prickly dogfish. They are ovoviviparous, and fecundity is low: one female contained seven embryos and 7 to 8 large ovarian eggs have been recorded in two New Zealand females. Young are born at about 24 cm. Males mature at about 55 to 60 cm and females at or before 67 cm. Maximum size is about 72 cm total length.
|Major Threat(s):||Taken as bycatch in bottom trawl fisheries, but extent of mortality unknown.|
|Conservation Actions:||There are currently no conservation measures in place for this species.|
