Bloop

Scientists have revealed a mysterious recording that they say could be the sound of a giant beast lurking in the depths of the ocean.

Researchers have nicknamed the strange unidentified sound picked up by undersea microphones "Bloop."

While it bears the varying frequency hallmark of marine animals, it is far more powerful than the calls made by any creature known on Earth, Britain's New Scientist reported on Thursday.

It is too big for a whale and one theory is that it is a deep sea monster, possibly a many-tentacled giant squid.

In 1997, Bloop was detected by U.S. Navy "spy" sensors 3,000 miles apart that had been put there to detect the movement of Soviet submarines, the magazine reports.
