生態學
海洋 底中水層性; 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. 西南大西洋: 到阿根廷烏拉圭.(參考文獻 58839)

Max length : 89.8 cm TL 雄魚/尚未辨別雌雄; (Ref. 55642); 94.3 cm TL (female); common length : 76.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 31367); common length :82 cm TL (female)
背棘 (總數) : 2; 臀棘: 0. 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 (Ref. 5578). Pearl-grey above, white below; fins with white edges, sides rarely with white spots (Ref. 5578).
一隻大的狗鯊具有一個長的, 有角的吻與一個小的嘴約略更超過一半的吻部長度; 沒有斑點的身體; 在胸鰭之上的第一背鰭棘.(參考文獻 5578) 背面珍珠灰色, 腹面白色的; 鰭有白色的邊緣, 側邊很少有白色的斑點。 (參考文獻 5578)
Found on the continental and insular shelves and upper slopes (Ref. 247, 75154). Perhaps ranging from 4-740 m (Ref. 58302). Feeds on bony fishes including hake, snoek, conger eels and lantern fishes (Ref. 36731), cephalopods, and crustaceans (Ref. 5213). Ovoviviparous (Ref. 205), with about 4 to 9 pups in a litter (Ref. 247).
棲息於大陸棚與島嶼棚與上層斜坡.。 (參考文獻 247) 在 29-600 公尺的大洋底棲性魚種, 也許從 4-740 公尺.(參考文獻 58302) 吃包括鱈魚，杖魚，康吉鰻與燈籠魚 (參考文獻 36731) ，頭足類動物與甲殼動物的硬骨魚類。 (參考文獻 5213) 卵胎生的 (參考文獻 205), 有大約 4 到 9個幼胎一胎.(參考文獻 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. Size at birth about 22 to 26 cm.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. 西南大西洋: 到阿根廷烏拉圭.(參考文獻 58839)
