For example, a blue whale can communicate with another blue whale using sound over thousands of miles across the sea. [6] While terrestrial animals often have a uniform method of producing and detecting sounds, aquatic animals have a range of mechanisms to produce and detect both vocal and non-vocal sounds. [7]
It appeared that both dolphins knew who they were speaking with and what they were speaking about. Not only do dolphins communicate via nonverbal cues, they also seem to chatter and respond to other dolphins' vocalizations. [28] Spectrogram of humpback whale vocalizations.

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.
Baleen whales - a group that includes the blue whale, the largest animal in Earth's history - use a larynx, or voice box, anatomically modified to enable underwater vocalization, researchers said ...
The melon is structurally part of the nasal apparatus and comprises most of the mass tissue between the blowhole and the tip of the snout. 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 ...
Research has recently shown that beaked and blue whales are sensitive to mid-frequency active sonar and move rapidly away from the source of the sonar, a response that disrupts their feeding and can cause mass strandings. [2] Some marine animals, such as whales and dolphins, use echolocation or "biosonar" systems to locate predators and prey.
Scientists think they might have finally learned the secret to how whales sing their complicated songs. We knew whales made a vast array of vocalizations, called songs, that can carry for ...
The UK whale and dolphin conservation charity Orca recorded 55,604 whales and dolphins in oceans worldwide in 2023 as part of a marine survey covering 330,000 kilometres with the support of ...
