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).
