How does it feel to be one of the few left in your own species on Earth? Anthropomorphizing aside, the heartbreaking story reflects the fact that the 52Hz whale species may never be seen again.

The story of the 52Hz whale has cast mysterious light on our finite understanding of the wildlife kingdom. The whale is named after the unique 52 Hz frequency of its call which differs it from other whales whose frequencies range from 10-39 Hz. In other words, this unusually high pitch in whale's world might have alienated the 52Hz to wander unknown before it was discovered in 1989.
Up to now, many things about the species are still unknown to us, including its size, its sound and how to reproduces. Its existence was found after it was recorded by a U.S. naval sonar during its migration from central California to the Aleutian Islands. 
Mystery still remains and the search continues to discover more about this seemingly lonely animal.
