52-Hertz Whale
whale 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 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.
The feature-length documentary The Loneliest Whale: The Search for 52, directed by Joshua Zeman, the director of Cropsey, and executive producers Leonardo DiCaprio and Adrian Grenier, was commercially released by Bleecker Street on July 9, 2021.
