Sitting squarely in the middle of our favorite sea monsters is a new entrant in the world of cryptic sea monsters, the Ningen. The Ningen is a recent sea monster reported by Japanese fishermen working in the Antarctic. Allegedly, Ningens are up to 30 meters long, have a human like body, and a tail. Reports of what they look like seem to vary quite a bit, but the one consistent bit is that they have a human face and other human features.
