Short Description
A large dogfish with a long, angular snout and a small mouth slightly more than half the snout length; body without spots; 1st dorsal fin spine over pectoral fins [536]. Pearl-grey above, white below; fins with white edges, sides rarely with white spots [536].

Distribution
Widely distributed in temperate and subtropical parts of most oceans but possibly consisting of a species complex [1388] [544]. Western Indian Ocean: Walters Shoal (MNHN 1991-0406) [20041]. Eastern Indian Ocean: southern Australia [1388]. Western Pacific: seamounts in the North Pacific, Japan, Korea, China (and presumably Taiwan and Viet Nam); possibly in New Zealand. Eastern Central Pacific: Hawaiian Islands. Nominal records of Squalus blainvillei or Squalus fernandinus from the western Indian Ocean, New Caledonia and Chile are based in part on this species. Elsewhere, dogfishes very similar to Squalus mitsukurii are not conspecific with Squalus blainvillei. Southwest Atlantic: Uruguay to Argentina [5839]. Source: www.gbif.org

Human uses
fisheries: minor commercial; price category: medium; price reliability: questionable: based on ex-vessel price for species in this genus

Biology
Ovoviviparous. Probably has 4 to 9 young per litter, most births in autumn, off the east coast of South Africa. There might be a gestation period of up to two years, and sexual segregation of females in the southern part of its range. Size at birth about 22 to 26 cm.

Habitat
benthopelagic; marine; depth range 29 - 600 m [17640], usually 48 - 533 m [19579]
