Circular mystery solved

In 2012, scuba diver Yoji Ookata made a very strange discovery at the bottom of the Pacific Ocean. What he saw appeared to be the ocean equivalent of crop circles. An advanced circular pattern of impressive intricacy and symmetry was carved into the sand and aroused the attention of the scientific community.

Those interested in pseudo-science and the paranormal also got involved and had many bizarre theories to explain where the pattern came from. The most popular theory among those in the pseudo-scientific community was that the pattern was made by extraterrestrial aliens. The pattern measured a diameter of 6 feet and was almost 80 feet below the sea level.

It would take specialist underwater construction equipment to create the pattern. Amateur archaeologists suggested that pattern may have been sand covering up an artefact from an ancient civilisation.

The circle mystery aroused such fervent debate and interest that an Asian TV news network even documented it. Debates raged over what the origins could be. Oceanographers and marine biologists eventually discovered the exact cause of the circle. They were in fact made by a puffer fish flapping its fins.

The female of this species is known to be attracted to hills and valleys. The more of these in her vicinity the more likely she would be to mate. Therefore, it is natural to conclude that a male puffer fish created the circular pattern.

This was to attract the female so the two could mate and create offspring. The two puffer fish would then lay their eggs in the middle of the circle. The grooves within the circle helped to stop currents from tossing the eggs around. So now we know thanks to science that the circles were made for a mating a ritual, as well as giving fish offspring extra protection.
