Answer:
Dolphins eat mainly hunting in pods. To hunt, they organize themselves following a very sophisticated procedure where everyone in the pod has its function.
The first technique is called herding, and it is performed by a pod of dolphins when some of they surround a school of fish making them as compact as possible before eating.
After this, the remaining dolphins take turns to pass through the fish from below and eat as much as possible in each pass.
Another way that dolphins use to eat is by conducting fish to shallow waters where they cannot escape, and there devour them.
