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.
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. Detail is shown for the first 24 seconds of the 37 second humpback whale ...
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]
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 bisected head of a dolphin: The melon is just above the upper jaw. Three-dimensional models of various odontocete melons based on CT scans. The melon is a mass of adipose tissue found in the foreheads of all toothed whales. [1] [2] It focuses and modulates the animal's vocalizations and acts as a sound lens.
Whale watchers got quite a show recently when one playful dolphin decided to show off for them in Monterey Bay, California. ABC News shared a clip on Sunday, March 24th of the whale watchers ...

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.
