* Fish: They are known to eat a wide range of fish species, including herring, cod, smelt, and squid.
* Squid: A significant part of their diet, particularly in areas where fish are less abundant.
* Crustaceans: Crabs, shrimp, and other crustaceans are also part of their diet.
* Other marine life: They may occasionally feed on other small marine animals like jellyfish and small sharks.
Their feeding habits are influenced by the season and location. They often use echolocation to locate prey in murky waters. They also work together in groups to herd fish into a concentrated area before feeding.
It's important to note that the specific prey species and their abundance vary depending on the region where the Commersons dolphin is found.
