Whale sounds are used by whales for different kinds of communication the mechanisms used to produce sound vary from one family of cetaceans to another marine mammals, such as whales, dolphins, and porpoises, are much more dependent on sound for communication and sensation than are land mammals, because other senses are of limited effectiveness in water.
