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 ...
[7] [8] [9] Because the calls have also been recorded from blue whale trios from in a putative reproductive context, it has been recently suggested that this call has different functions. [10] The blue whale call recorded off Sri Lanka is a three‐unit phrase. The first unit is a pulsive call ranging 19.8 to 43.5 Hz, lasting 17.9 ± 5.2 s.
Over the last 50 years blue whales have changed the way they are singing. Calls are progressively getting lower in frequency. For example, the Australian pygmy blue whales are decreasing their mean call frequency rate at approximately 0.35 Hz/year. [42] The migration patterns of blue whales remain unclear.
Still, uncovering the scope of whales’ vocal exchanges is an important step toward linking whale calls to specific messages or social behaviors, the scientists reported May 7 in the journal ...

The Loneliest Whale: The Search for 52 is a 2021 American documentary film, directed, written, and produced by Joshua Zeman. Leonardo DiCaprio and Adrian Grenier serve as executive producers. The film follows a group of scientists in search of the 52-hertz whale , a whale which is believed to have spent its life in solitude, calling out at a ...
Some sources distinguish between simpler vocalizations, termed “calls”, reserving the term “song” for more complex productions. [2] Song-like productions have been identified in several groups of animals, including cetaceans (whales and dolphins), avians (birds), anurans (frogs), and humans. Social transmission of song has been found in ...
