DRC - Dolphin Communications Dolphin Research Center Dolphin Communications Communication in bottlenose dolphins appears to be extensive and complex.
Dolphins hunt together to find food.
Pods of dolphins coordinate their movements to herd prey, then take turns swimming into the middle of the assembled fish to eat. There is still much to learn about how dolphins communicate though a number of generalities have emerged from research. Since water transmits sound so much better than air it stands to reason that dolphins rely on sending and receiving in-water sounds for communication more than any other mode. Each dolphin seems to develop a distinctive high-pitched whistle which scientists are calling a signature whistle. This appears to serve as a means of individual identification.
