生态学
海洋; 半咸淡水 居于水底的; 深度上下限 15 - 1500 m (Ref. 125614). 亞熱帶的; 11°C - 18°C (Ref. 54892); 50°N - 37°S, 20°W - 38°E (Ref. 54892)
Eastern Atlantic: Bay of Biscay to Mediterranean, Morocco, Senegal to Namibia (these records may include other species in addition to Squalus blainvillei). Although reported from the Canary Islands (e.g. Ref. 247), it is most likely based on misidentifications of Squalus megalops (Ref. 6808). Western Pacific: southern Japan and Taiwan. Nominal records of Squalus blainville or Squalus fernandinus from the western Atlantic (North Carolina, USA to northern Gulf of Mexico; Argentina), Indian Ocean (South Africa, Mozambique, Madagascar, Tanzania and India) and the Pacific (Australia, New Zealand, New Caledonia, Hawaii and northern Chile), as well as some records from the northwest Pacific and eastern Atlantic are based at least in part on Squalus mitsukurii and possibly other species. Whether Squalus blainville itself is as wide-ranging as reported for blainville-group dogfishes (including Squalus mitsukurii) remains to be determined.
東大西洋: 比斯開灣到地中海，摩洛哥, 塞內加爾到那米比亞.(這些記錄可能以及 Squalus blainvillei 包括其他的種) 雖然記錄自加納利群島 (例如參考文獻 247), 它是很有可能以 Squalus 大眼幼蟲 的誤鑑為依據.(參考文獻 6808) 西太平洋: 日本南部與台灣。 Squalus blainvillei 或 Squalus fernandinus 從大西洋西部的分類命名紀錄 (美國北卡羅萊那州到墨西哥灣北部; 阿根廷), 印度洋 (南非，莫三比克，馬達加斯加, 坦尚尼亞與印度) 與太平洋 (澳洲，紐西蘭，新加勒多尼亞, 夏威夷與智利北部), 以及一些來自西北太平洋的紀錄與東大西洋的至少有一部份是指 Squalus mitsukurii 與可能其他的種。 Squalus blainvillei 本身是否是一樣廣泛分佈如那為 blainvillei 報告 -群的狗鯊 (包括 Squalus mitsukurii) 仍待決定。
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 57.1, range 57 - 58 cm
Max length : 122 cm TL 雄鱼/尚未辨别雌雄; (Ref. 86318); 117.5 cm TL (female); 最大体重: 7.3 kg (Ref. 86318)
Found on the continental shelves and upper slopes. Depth range from 16-440 m (Ref. 0247), and from 300-780m in the eastern Ionian Sea (Ref. 56504). Forms schools. Off West Africa, water temperature and salinity where this species is often found ranges from 11-18°C and 36 ppt. (at 16 to 255 m depth), respectively. Feeds on bony fishes, like denticids, mackerel and percichthyids, as well as crabs, lobsters, and octopi. Ovoviviparous, with 3 to 4 young per litter. Utilized fresh, dried salted and smoked for human consumption.
栖息于大陆棚与上层斜坡了。 来自 16-440 公尺 (参考文献 0247) 的深度范围, 与从 300-780 公尺在爱奥尼亚的海洋东部中.(参考文献 56504) 形成鱼群。 非洲西部外, 这种时常发现范围从 11-18 °C 与 36个 ppt 的水温与盐度。 (在 16 到 255 公尺深), 分别地。 吃硬骨鱼类, 像 denticids ，鲭与真鲈科鱼类, 以及螃蟹，龙虾与章鱼。 卵胎生的, 3 到 4个幼鱼每胎。 生鲜使用, 干燥盐腌而且烟熏了供人类消费。
