生态学
海洋 底中水层性; 深度上下限 29 - 600 m (Ref. 58302), usually 48 - 533 m (Ref. 57911). 深水域; 8°C - 17°C (Ref. 57911); 45°N - 55°S, 97°W - 164°W (Ref. 54897)
Circumglobal in temperate and subtropical waters: Widely distributed in most oceans but possibly consisting of a species complex (Ref. 6871, 31367). Western Indian Ocean: Walters Shoal (MNHN 1991-0406) (Ref. 33390); Eastern Indian Ocean: southern Australia (Ref. 6871); West Pacific: Seamounts in the North Pacific, Japan, Korea, China (and presumably Taiwan and Viet Nam); Southwest Pacific: possibly in New Zealand; Southeast Pacific: Desventuradas Is. and Juan Fernández Is. Southwest Atlantic: Uruguay to Argentina (Ref. 58839). 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.
廣泛地分佈於溫帶與亞熱帶的大多數海域中但是可能包含一個複合種.(參考文獻 6871,31367) 西印度洋: 沃爾特淺灘 (MNHN 1991-0406).(參考文獻 33390) 東印度洋: 澳洲南部.(參考文獻 6871) 西太平洋: 北太平洋的海底山脈，日本，韓國, 中國;(與可能台灣與越南) 可能地在紐西蘭。 中太平洋東部: 夏威夷群島。 Squalus blainvillei 或 Squalus fernandinus 從西印度洋的分類命名紀錄, 新加勒多尼亞與智利有一部分是指這一個種。 在別的地方，狗鯊非常類似 Squalus mitsukurii 不是與 Squalus blainvillei 同種.

Ovoviviparous (Ref. 205), with about 4 to 9 pups in a litter (Ref. 247).

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.
