In 1995, strange 7-foot circular patterns were discovered on the ocean’s floor. Deemed the ‘crop circles of the sea’, these mysterious patterns went unanswered for until early 2011 when it was discovered that 5-inch long male puffer-fish were the culprits. After studying these animals, scientists have discovered that the meticulous creation and upkeep of these patterns by the puffer-fish serve as an attraction for the opposite sex as well as a nest for the female puffer-fish’s eggs.
