Since the '90s, crew members on Japanese research vessels in the Antarctic have reported multiple sightings of a giant ice creature they call the “Ningen.”
These figures are usually described as pure white, measuring up to 100 feet long, and vaguely humanoid in appearance, although they seem to lack facial features and some are reported to have fins, flippers or mermaid-like tails.
Rumors spread via Japanese online forum 2channel, eventually catching the attention of paranormal research magazine MU, who in 2007 posted a Google Maps image of a white whale-like shape in the South Atlantic.
Sites like Pink Tentacle and Mysterious Universe have offered many theories about the Ningen, but so far nothing conclusive has been found. Videos purported to be visual documents of the creature have also been circulating, including the clips below:
