Extra Distribution Information
Moreton Bay, QLD to Geraldton, WA; numerous observational records indicate a much broader distribution, particularly from offshore areas in Queensland and Western Australia, but these records are unconfirmed and probably based on more than one species; temperate, circumglobal (except central Pacific), antitropical.
