Dusky Dolphin

A small dolphin with a short beak, dark back and pale underside, the dusky dolphin is recognised by its sweeping grey-and-white flank pattern. The dorsal fin is moderately curved. This is a different animal from the compact, sharply black-and-white Commerson’s dolphin of nearby coastal waters.

In northern Patagonia, groups can cooperate to concentrate and catch schooling fish, particularly anchovy. Surface activity may attract seabirds, and dolphins can change their position as prey moves. Research in Golfo Nuevo has documented this feeding behaviour, making the gulf an important part of the species’ regional story.

In our region. A documented inhabitant of Golfo Nuevo. Summer and early-autumn boat outings offer a relevant observation context, but operating dates, sea conditions and group locations must be checked rather than assumed.
