Forget Nemo, someone needs to find this whale a friend! It has been tracked since 1992 and been labeled the loneliest whale in the world. Nicknamed "the 52 Hertz whale", it sings at a frequency of 51.75 Hz whereas others of it's kind sing at 15 - 25 Hz. To make a long story short, no one else can hear it; the frequency is completely different.
To make matters worse, it does not travel along migration routes of any baleen whale species. There is no opportunity for other whales to run into it along migration paths. For almost 2 decades the NOAA has been using "classified array of hydrophones employed by the Navy to monitor enemy submarines" to listen to it's desperate cries for attention trying to find a mate, friends, or anyone/thing that will listen. This simply breaks my heart.
"The best guess of researchers is that this lonely whale is either a 'deformed' hybrid between 2 species of whale, or the last surviving member of an unknown species." - Impact Lab
According to The New York Times article, the whale calls out at the regularity of a metronome. Now that is persistence. However, over time the notes have become to get a bit deeper and some feel it may be linked to sadness and despair. I hope that one day this whale bumps into another because everyone needs a friend! Even whales that sing their own tune :)
