生態學
海洋 居於水底的; 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).
