Somewhere out in the Pacific Ocean swims what is said to be the loneliest whale in the world. He (or she, but here I’m going to assume he) is known as the 52-hertz whale. That designation comes from the sound of his whale song, which has a much higher pitch than any known species fitting his migratory pattern.
His calls were first heard by Woods Hole in 1989 and again in 1990 and 1991. His cries have been detected every season since 2004. His movements (he’s been tracked, but never seen) don’t match blue or fin whales any more than his cries do. One theory is that he was born deaf and never learned to sing like others of his species.
All of which gives me a real affinity for the poor guy!
