Commerson's Dolphin


Behavior Observation

For the most part, Commerson's dolphins in the wild are visible only when they are at the surface, so it is inherently challenging to document and study dolphin behavior.

Social Structure

Commerson's dolphins are typically found alone or in small groups of two to three individuals.

  • Other observers report groups of 2 to 15, 20 to 30, and on rare occasion, groups of 100 or more Commerson's swimming together. 

Social Behavior

Little is known about Commerson's dolphin movements from one area to another. Seasonal movement may be due to food availability.
