The Ningen is a name given to a group of limbed sea mammals which have not yet been properly documented. These creatures are well known by the Japanese scientists and fisherman, whom have seen them often and have been filmed numerous times in the arctic region. Included are a few samples. They are understood to be a product of evolution not unlike the seal, these creatures have more pronounced limbs which allow them to surface travel more and pull themselves up onto the ice. Little is known about these creatures which seem to be mammals and range in size from the size of a seal to larger then any known whale.
