There is a whale known as the "The Loneliest Whale in the world" because it can't communicate in the same frequency as other whales.

The Loneliest Whale in the World.
As I was lost in the image world of Pininterest, I stumbled upon an image of the Loneliest Whale in the World.  In 2004, The New York Times wrote an article about how, since 1992, scientists have been tracking a baleen whale named, “The 52 Hertz Whale.”  She swims and sings alone in our earth’s vast ocean:

Not heard nor seen

She isn’t like any other baleen whale. Unlike all other whales, she doesn’t have friends. She doesn’t have a family. She doesn’t belong to any tribe, pack or gang. She doesn’t have a lover. She never had one.

Her songs come in groups of two to six calls, lasting for five to six seconds each. But her voice is unlike any other baleen whale. It is unique—while the rest of her kind communicate between 12 and 25hz, she sings at 52hz. You see, that’s precisely the problem. No other whales can hear her. Every one of her desperate calls to communicate remains unanswered. Each cry ignored. And, with every lonely song, she becomes sadder and more frustrated, her notes going deeper in despair as the years go by.

Unsurprisingly not only is her song indecipherable to other whales, she also likewise doesn’t follow the standard migration routine involving it's kinds, rendering it actually less likely to connect with others.

Just imagine that massive mammal, floating alone in addition to singing—too massive to connect having the beings this goes by, sensation paradoxically little in the vast stretches of empty, open ocean.
