A spectrogram of the 52-hertz signal

The 52-hertz whale is an individual whale of unidentified species which calls at the unusual frequency of 52 Hz. This pitch is 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 (10–39 Hz)[2] or fin whale (20 Hz).[1] Its call has been detected regularly in many locations since the late 1980s and appears to be the only individual emitting a whale call at this frequency. However, the whale itself has never been sighted, it has only been heard via hydrophones. It has been described as the "world's loneliest whale".[3][4]


The sonic signature is that of a whale, albeit at a unique frequency. At 52 hertz, it is a little higher than the lowest note on a double bass. The call patterns resemble neither blue nor fin whales, being much higher in frequency, shorter, and more frequent.[5] Blue whales usually vocalize at 10–39 Hz,[2] fin whales at 20 Hz.[1] The 52-hertz calls of this whale are highly variable in their pattern of repetition, duration, and sequence, although they are easily identifiable due to their frequency and characteristic clustering.[6] The calls have deepened slightly to around 50 hertz since 1992, suggesting the whale has grown or matured.[4]

The migration track of the 52-hertz whale is unrelated to the presence or movement of other whale species.[7] Its movements have been somewhat similar to that of blue whales, but its timing has been more like that of fin whales.[6] It is detected in the Pacific Ocean every year beginning in August–December, and moves out of range of the hydrophones in January–February. It travels as far north as the Aleutian and Kodiak Islands, and as far south as the California coast, swimming between 30 and 70 km each day.[citation needed] Its recorded distance traveled per season has ranged from a low of 708 km to a high of 11,062 km in 2002–03.[8]

Scientists at the Woods Hole Oceanographic Institution have been unable to identify the species of the whale. They speculate that it could be malformed or a blue whale hybrid.[7] The research team is often contacted by deaf people who wonder whether the whale may also be deaf.[9]

Whatever biological cause underlies its unusually high frequency voice does not seem to be detrimental to its survival. The fact that the whale has survived and apparently matured indicates it is probably healthy. Still, its unique call is the only one of its kind detected anywhere and there is only one such source per season.[8] Because of this, the animal has been called the loneliest whale in the world.[5][10][11]

The 52-hertz whale was discovered by a team from the Woods Hole Oceanographic Institution. Its call was first detected in 1989, then again in 1990 and 1991.[8] In 1992, following the end of the Cold War, the U.S. Navy partially declassified the recordings and technical specifications of its SOSUS anti-submarine hydrophone arrays, and made SOSUS available for oceanographic research.[6][7] As of 2014, the whale had been detected every year since.[12]

In art[edit]


The Loneliest, a short mockumentary film about two women searching for the loneliest whale, was made in April 2014 by Lilian Mehrel, with the Alfred P. Sloan Foundation.[13][14]

The title of the Taiwanese movie 52Hz, I Love You (2017) is inspired by the whale, using it as a metaphor for the loneliness experienced when looking for love.

Stare Yıldırım's 2018 film My Name is Batlir, Not Butler features the 52-hertz whale as both a character (mostly represented by a photo and voice-over) and as a metaphor for the loneliness of those who are different.[15]

The animated short film entitled The Phantom 52 premiered at the Sundance Film Festival in January 2019. The film is written and directed by Geoff Marslett, and stars Tom Skerritt as the loneliest whale. The Phantom 52 went on to play at over 60 film festivals worldwide and win a half dozen awards.[16][17]

A feature-length documentary entitled The Loneliest Whale: The Search for 52, directed by Joshua Zeman, the director of Cropsey, and produced by Adrian Grenier, was commercially released on July 9th, 2021. Funded through a Kickstarter campaign,[18] the film was due for release sometime in 2018 but was delayed.[19][20]


Andy Othling under the name of Lowercase Noises released an EP called "Migratory Patterns" in 2011. The album "... is a collection of songs written as a chronicle of the story of the famed 52Hz whale."[21]

Montreal-based saxophone player and composer Colin Stetson's 2013 album New History Warfare Vol. 3: To See More Light included a song entitled "Part of Me Apart From You". Though not explicitly written about the 52-hertz whale, when first performing the song live, he has remarked on at least several occasions that the story of the "loneliest whale" resonated deeply with his composition. "This whale is alone in a large body of water, swimming, singing its song, calling for a likeness it will never find," he said by way of introducing the song at a performance at Toronto's Great Hall on 19 May 2013. "When I play this song, I can't help but think about this whale, who right at this very minute is singing alone."[22]

South Korean group BTS's 2015 album The Most Beautiful Moment in Life, Pt. 2 includes the track "Whalien 52", which explicitly uses the 52-hertz whale as a metaphor for the alienation from others often felt by adolescents.[23]

The English folk duo Kathryn Roberts and Sean Lakeman included the song "52 Hertz" on their 2015 album Tomorrow Will Follow Today. The song is about the whale and includes the line, "52 Hertz, 52 Hertz, I'm singing a love song that no-one can hear" in the chorus.[24]

In 2016, No Land (a music group made up of Azerbaijani, Iranian, Kurdish and Turkish musicians) released 52 Hertz Whale - Outro.

In 2017, Zhou Shen released a song called "A Lonely Blue Whale Living Like an Island" or "化身孤岛的鲸", inspired by the whale.

In 2018, American singer Chrysta Bell released a song called "52 Hz", inspired by the whale.[25]

In 2021, Amber Run released a song called "52 Blue."


In 2017, Jessica Therrien and Dorene Uhrich published a book titled "The Loneliest Whale."

In 2015, Matt Dahl, editor of Chatsworth Press, published the anthology "Lonely Whale Memoir"[26]

In 2020, Japanese novelist Sonoko Machida published a novel titled 52-Hertz Whales, in which the anomalous whale serves as a metaphor for "voiceless" lonely people who find each other by chance.[27]
