The Oarfish.

They say it’s harmless. But seriously, look at the size of that thing.

Another sea creature: the 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.

You can listen to the sound yourself here. Of course, some people have noticed that the Bloop, heard in the South Pacific, shares a zip code with H.P. Lovecraft’s fictional Lost City of R’lyeh.

This site yielded not only a .wav file of the noise itself, but the fact that the sound is believed to be coming roughly from 50oS; 100oW. After reading that, I wondered how close that was to the coordinates given in “The Call of Cthulhu”. Allow me to quote: “Then, driven ahead by curiosity in their captured yacht under Johansen’s command, the men sight a great stone pillar sticking out of the sea, and in S. Latitude 47°9′, W. Longitude l23°43′, come upon a coastline of mingled mud, ooze, and weedy Cyclopean masonry which can be nothing less than the tangible substance of earth’s supreme terror – the nightmare corpse-city of R’lyeh, that was built in measureless aeons behind history by the vast, loathsome shapes that seeped down from the dark stars.”

Which means only one thing. That’s right, kids: Cthulhu.

Somehow it always comes back to Cthulhu.
