Previously known primarily from the southern coast of eastern South America, from Uruguay and southern Brazil to Tierra del Fuego, this species is now known from offshore in the southern Hemisphere (Brownell and Clapham 1999). There are records from the Falkland Islands, South Georgia, Kerguelen Islands, Heard Island, Macquarie Island, and the Auckland Islands. Although rarely seen at sea (there are only a few dozen live sightings), this information suggests that the spectacled porpoise’s range may be circumpolar in the sub-Antarctic zone (with water temperatures of at least 1-10°C) (Goodall 2002). The southernmost sighting is from 64°34'S.
