Also called “the world’s loneliest whale,” the 52-Hertz whale was first recorded in 1989. Its song was deemed unusual because it’s higher than a traditional blue whale or fin whale song, though other elements of the song are similar to those of blue whales. Some scientists believe that this whale may simply be singing in a regional dialect that hasn’t been heard before, whereas others say that it may be entirely unique. Many hypothesize that the whale is a hybrid of two species. One popular misconception about it is that other whales cannot hear its strange song. However, that’s false—the 52-Hertz whale’s singing might be odd, but it’s perfectly audible to blue, fin, and humpback whales.
