Bowhead whale (Balaena mysticetus) Bowhead whales are highly vocal [21] and use low frequency (<1000 Hz) sounds to communicate while travelling, feeding, and socialising. Intense calls for communication and navigation are produced especially during migration season. During breeding season, bowheads make long, complex, variable songs for mating ...
While the complex sounds of the humpback whale (and some blue whales) are believed to be primarily used in sexual selection, [5] there are simpler sounds that are created by other species of whales that have an alternative use and are used all year round.

[a] The blue whale's long and slender body can be of various shades ...
The 52-hertz whale, colloquially referred to as 52 Blue, is an individual whale of unidentified species that calls at the unusual frequency of 52 hertz. This pitch is at a higher frequency than that of the other whale species with migration patterns most closely resembling the 52-hertz whale's [1] – the blue whale (10 to 39 Hz) [2] and the ...
While the audio profile of Bloop does resemble that of a living creature, [4] the source was a mystery both because it was different from known sounds and because it was several times louder than the loudest recorded animal, the blue whale. [5] The NOAA Vents Program has attributed Bloop to a large icequake. Numerous icequakes share similar ...
The blue whale was not the only marine life passengers saw on the trip. Laurino said they observed about 20 fin whales, pilot whales, several dolphin species, a manta ray that breached the surface ...

The interactions between marine mammals and sonar have been a subject of debate since the invention of the technology. Active sonar, the transmission equipment used on some ships to assist with submarine detection, is detrimental to the health and livelihood of some marine animals. [1] Research has recently shown that beaked and blue whales are ...
