Dolphins get their food mainly using two smart techniques which require a highly coordinated team job.
The first one is called herding, usually performed by a group of dolphins who surround a school of fish to pack them as tightly as possible.
After this, all dolphins take turns to pass through the concentration of fish and feed one at the time while the others keep the school of fish as packed as possible, making each turn through the school of fish more efficient to grab the largest number possible of fish.
The other technique for feeding used by dolphins is called corralling, a method used when a school of fish chased by a group of dolphins is taken to shallow waters where they cannot escape, keeping them close to the shore and surrounded by the pod of dolphins who pushed them there.
After this, dolphins simply catch these fishes also taking turns to eat.
