If you are curious about aliens and extraterrestrial life, you’ve probably heard a lot about crop circles, but surprisingly a Japanese photographer Yoji Ookata has found something similar to crop circles 80 ft below the sea level. He discovered this 6.5 feet mysterious circle carved from sand while diving. He was so amazed that he came back with the TV Crew to figure this out.
Wait, there is no alien theory behind it.
The cameras revealed that there is no alien theory behind this. A few-inch long puff fish was creating the sand sculptures by swimming tirelessly and using its single fin. The team figured that this is the way to attract the male fish, and the center of the circle is where the pair lays the eggs. The riffles serve as a protective barrier against ocean currents.
