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

Lingkungan: lingkungan / zona iklim / kisaran kedalaman / jangkauan distribusi Ekologi

laut dasar (demersal); kisaran kedalaman 30 - 750 m (Ref. 27121), usually 80 - 300 m (Ref. 57911). Subtropical; 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).
