A lone whale that makes sounds unlike any known species has marine biologists baffled. The whale has been wandering the Pacific for 12 years, but scientists have been unaware of it because its voice was only being picked up by classified US Navy equipment.
Using declassified data, marine biologists have determined that the whale’s voice, pitched at 52 hertz, does not match any known species. Whales generally call between 15 and 20 hertz. While some species use higher frequencies, none are near 52 hertz.
The calls have gotten deeper over the years, suggesting that the whale has matured. Marine biologists doubt that the whale represents a new species. No call like it has been heard anywhere in the world.
