There have been numerous mysterious underwater noises picked up by the National Oceanic and Atmospheric Administration (NOAA);“The Bloop” is one of them. The Director of the NOAA at the time of the recording of “The Bloop” speculated that the noise was indeed from an animal, although the noise was much louder than the loudest animal noise, that of the largest animal known to exist-the 100 ft. blue whale. That would mean some unknown creature likely larger than what we think is the largest animal is out there lurking in the unchartered abyss.
