All cetaceans, that is whales, dolphins, and their relatives, can produce sound. Toothed whales, which include the dolphins, killer whales, porpoises, and the sperm whale, produce high-frequency sounds that are useful for echolocation. Baleen whales produce sounds that are lower frequency than toothed whales, and these are primarily used in communication. The low-frequency sounds that baleen whales produce are among the loudest sounds that are produced by animals on the planet.
