Junior synonym Squalus acutipinnis Regan, 1908 is considered a valid species in Ref. 109601, 130168.

生态学
海洋 居于水底的; 深度上下限 30 - 750 m (Ref. 27121), usually 80 - 300 m (Ref. 57911). 深水域; 9°C - 23°C (Ref. 57911); 42°N - 60°S, 100°E - 140°W (Ref. 247)
Eastern Indian Ocean: previously considered to be an Australian endemic (Ref. 49645). Eastern Atlantic: confirmed to occur in the Mediterranean (Ref. 93472). Dogfishes presently referred to in current literature as Squalus megalops appear to belong to a complex of similar species. Specimens from the different regions still need to be compared carefully (Ref. 6871).
東印度洋: 狀似一個澳洲的特有種。 狗鯊目前在現在的文件中被稱為 Squalus 大眼幼蟲 似乎屬於一個相似種的複合體。 標本從不同的區域仍然需要小心地被比較.(參考文獻 6871)

Found on the outer continental shelves and upper slopes, on or near the bottom (Ref. 31367); sublittoral below 130 m (Ref. 11230). Young mostly pelagic off the outer shelves (Ref. 5578). Aggregations by sex are regularly observed (Ref. 6871). Feeds on bony fishes, shrimps and other crustaceans, cephalopods and other elasmobranchs (Ref. 247). Ovoviviparous (Ref. 205), with 2 to 4 young in a litter (Ref. 247). Gestation period is 2 years (Ref. 36731). Utilized for human consumption, the flesh most appealing dried salted or smoked (Ref. 6871). Also consumed fresh (Ref. 31367). Minimum depth reported from Ref. 6808.
