Analyzed a part of the principle that a puffer fish creates a mystery circle


A mystery circle with a diameter of about 2 meters that suddenly appears at the bottom of Amami Oshima. A puffer fish of 10cm length constructs it without using any tool. HW students and member analyzed the method of the pufferfish by the behavioral analysis and the computer simulation. The most interesting point is the logic that the repeat of the very simple behavior emerges a complex geometric structure. this study was done by the cooperation between an ethnologist and the group of students with different expertise.

The result of this research was published on UK scientific journal “Scientific Reports” (online).
