The seven foot diameter patterned circles that were discovered on the ocean floor off the coast of Japan in 1995 are termed as the underwater crop circles by many. Like the on-field crop circles, these underwater crop circles has also been very mysterious, as no one know that how these got built and people associated the creation of these patterned underwater circles with aliens. However, scientific studies of these circles have revealed that these are hoaxes and man-made circles. Here are five such evidences that will debunk the underwater crop circles.
(1) By the beginning of the 21st century it was discovered that the creators of the underwater crop circles were a new species of puffer fish. The small puffer fishes were found to be making these circle patterns on the ocean floor to attract their mating partners. The fin flapping of the male puffer fishes as they swim across the seafloor results in disrupted sediments and creation of amazing circular patterns. The female fishes would inspect the patterns and if they liked the pattern, that is when they would go ahead with the reproduction process with the male puffer fish.
(2) Looking at the huge size of the underwater circular patterns it might look that the patterns are made by fishes that quite big in size. The reality, however, is that the patterns are made by puffer fishes which are very small in size and do not have a length of anything more than a couple of inches.
