Crustaceans and Invertebrates: Depending on location, dolphins may also consume shrimp, crabs, octopuses, and small jellyfish.

-
Cooperative Strategies: Some dolphins work together to flush fish from reefs or create waves to wash shore fish onto the sand.
-
Individual Skill: Young dolphins learn hunting techniques by observing and mimicking elders, showing strong cultural transmission in feeding behaviors.
