Just recently, Japanese photographer Yoji Ookata discovered what he called a “mysterious circle” at the waters of Amami Oshima. Lying about 80 feet below sea level and measuring nearly six feet in diameter, this circular figure sparked his interest.
Together with a team of divers from Japanese nature program NHK, they went to the place to figure out where these circles came from.
Nature really has its wonders because the beautiful and mysterious circle was found out to be made by the small creature pictured below.
This little puffer fish was observed swimming in circles endlessly, creatively making the circle. Experts explained this activity as very important because, apparently, this is how the fish attracts mates.
Female fish are said to be attracted to valleys and hills within the sand. With the use of the circle, they can now find the male fish. Eventually, the female will lay her eggs in the middle of the circle.
Scientists also concluded that the more ridges and valleys the circle has, the more chances that fish mating might occur.
