Dolphins are highly social animals, often living in pods of up to a dozen individuals. what kinds of behaviors have been studied in these pods to demonstrate their interdependence and social exchanges?

It is through whistles that dolphins interact with the pod. Each dolphin has a distinct whistle that identifies it with other dolphins of its pod. If an individual is in danger, it uses a particular noise that indicates aid is needed, so the pod responds quickly.

Small dolphin species gather into multi-member pods as a way to compensate for their size when facing predators.
