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].

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

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