Southeast Pacific and Southwest Atlantic: southern Chile, southern Argentina, and the Falkland Islands Reported from off the western Cape coast but the identity of South African specimens is questionable (the correct species may be Etmopterus baxteri Garrick, 1957). Presence in the Western Pacific uncertain (Ref. 31367). Eastern hemisphere records doubtful (Compagno 1999, pers.comm.).

Length at first maturity / Size / Weight / Age
