Japan crop circles have been discovered underwater off the coast of the southern Japanese island of Anami Oshima, drawing reports that it may have been caused by UFO's.
It's a circular pattern of rippling sand about 80 feet below sea level and 6 feet in diameter was on the ocean floor. A film crew from the Japanese broadcaster NHK went back to film this creation to find out what was creating this formation.
The crew found out that the entire structure was carved out by a single male pufferfish, tirelessly swinging his fin in the sand to create the grooves and ridges of the structure, which is many times the size of his own body. They also found that beyond just carving out the repeating shapes, he was also decorating the structure as he built it, peppering it with small stones and seashells.
The tiny fish works tirelessly day and night to complete the design. While the circled sculpture is beautiful to look at, Ookata and his crew learned that the fish's creation maintained a dual purpose. Female fish are attracted to the ridges and valleys left in the sand, and they deposit their eggs in the center. The eggs are then shielded from the ocean currents, as the higher points of the sculpture create a barrier to protect them.
The more ridges a sculpture contains, the more likely it will attract the females of the species. This discovery really just scratches the surface of knowledge about the ocean. The rest of the 95 percent still awaits exploration.
