Human acoustic tools can distinguish individual whales by analyzing micro-characteristics of their vocalizations, and the whales can probably do the same. This does not prove that the whales deliberately use some vocalizations to signal individual identity in the manner of the signature whistles that bottlenose dolphins use as individual labels.
The basic functions of communication in aquatic animals are similar to those of terrestrial animals. In general, communication can be used to facilitate social recognition and aggregation, to locate, attract and evaluate mating partners and to engage in territorial or mating disputes. Different species of aquatic animals can sometimes communicate.

The function of the melon is not completely understood, but scientists believe it is a bioacoustic component, providing a means of focusing sounds used in echolocation and creating a similarity between characteristics of its tissue and the surrounding water ...
