Searching for ‘The Loneliest Whale’ who can’t communicate with others

Humans don’t know much about what whales do underwater, but we do know that they are social and they communicate through song. But one whale seems to be the only one speaking his language as he communicates at the 52 hertz frequency. This whale is named “52,” and the search for him is the subject of a new documentary, called “The Loneliest Whale.”
