The Dusky Dolphin is distributed in coastal waters of Chile, Argentina and the Malvinas Islands, Namibia and the west coast of South Africa and all around New Zealand. There may also reside in populations off Tasmania and New South Wales and several small islands in the South Atlantic and Indian Oceans. An aerial survey off Patagonia in the mid-1990s indicated that there was a local population in excess of 7,000 individuals. Duskies can move over great distances (one individual had a confirmed range of 780 nautical miles) . However it is not believed that they follow a migratory pattern.
