Southern Right Whale Dolphins have a circumpolar distribution in the Southern Hemisphere (Jefferson et al. 2015, Lipsky and Brownell 2018). They are found only in cool temperate to sub-Antarctic waters, mostly between about 25°S and 65°S. They are observed most often between the subtropical and Antarctic convergences, with a distribution reflecting the variability in these oceanic features (Gaskin 1968). The southern limit appears generally to be bounded by the Antarctic Convergence. The range extends furthest north along the west coast of South America; the northernmost record is at 12°S off northern Peru (Van Waerebeek et al. 1991). The species generally occurs far from shore, and the majority of the range is in international waters of the Southern Ocean. However Southern Right Whale Dolphins have been recorded in the Exclusive Economic Zones of Australia, New Zealand, South Africa, Namibia, Mozambique, Chile, Argentina, Brazil and Peru (Jefferson et al. 2015).
