生態學
海洋; 半鹹淡水 居於水底的; 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 / 年齡
Maturity: Lm 57.1, range 57 - 58 cm
Max length : 122 cm TL 雄魚/尚未辨別雌雄; (Ref. 86318); 117.5 cm TL (female); 最大體重: 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.
棲息於大陸棚與上層斜坡到至少 440 公尺了。 形成魚群。 非洲西部外, 這種時常發現範圍從 11-18 °C 與 36個 ppt 的水溫與鹽度。 (在 16 到 255 公尺深), 分別地。 吃硬骨魚類, 像 denticids ，鯖與真鱸科魚類, 以及螃蟹，龍蝦與章魚。 卵胎生的, 對 4個幼魚有三個每胎。 生鮮使用, 乾燥鹽醃而且煙燻了供人類消費。
