About The Commerson's dolphin

Commerson's dolphins are primarily found in the coastal waters of the southwest Atlantic Ocean near Patagonia, Tierra del Fuego, Cape Horn and the Falklands Islands. They are most commonly seen along the eastern coast of South American between 41˚30' S and 55˚ S latitude, though they have been found as far north as 31˚ S latitude in some areas.

There is also a disjunct population of Commerson's dolphins in the south Indian Ocean near Kerguelen Island. In this area, they range from 48˚30' S to 49˚45' S latitude and are most common around the Golfe du Morbihan and around Heard Island. They are the only common cetacean in these coastal waters.
