The blue whale call recorded off Madagascar, a two‐unit phrase, [12] starts with 5–7 pulses with a center frequency of 35.1 ± 0.7 Hz and duration of 4.4 ± 0.5 s followed by a 35 ± 0 Hz tone lasting 10.9 ± 1.1 s. [11]
Humpback whale, sound spectrum and time plots. Whales occupying the same geographical areas (which can be as large as entire ocean basins) tend to sing similar songs, with only slight variations. Whales from non-overlapping regions sing entirely different songs. [12] As the song evolves, it appears that old patterns are not revisited. [12]
It is one of Earth's most haunting sounds - the "singing" of baleen whales like the humpback, heard over vast distances in the watery realm. Baleen whales - a group that includes the blue whale ...
The record-holder blue whale was recorded at 173 tonnes (190 short tons), [56] with estimates of up to 199 tonnes (220 short tons). [57] In 2024, Motani and Pyenson calculated the body mass of blue whales at different lengths, compiling records of their sizes from previous academic literatures and using regression analyses and volumetric analyses.
All baleen whales use sound for communication and are known to "sing", especially during the breeding season. Blue whales produce the loudest sustained sounds of any animals: their low-frequency (infrasonic, under 20 Hz) moans can last for half a minute, reach almost 190 decibels, and be heard hundreds of kilometers away. Adult male humpbacks ...
Before extensive research on whale vocalizations was completed, the low-frequency pulses emitted by some species of whales were often not correctly attributed to them. Dr Payne wrote: "Before it was shown that fin whales were the cause [of powerful sounds], no one could take seriously the idea that such regular, loud, low, and relatively pure frequency tones were coming from within the ocean ...

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 ...
