While the famous animation Finding Nemo has stolen many hearts world over, the Japanese Fish in real might just be the next big thing in the Fish world (if there were one of course)
The fish is called a Puffer fish, which can inflate into a ball shape to evade predators. Also known as blowfish, this particular little one is capable of creating elaborately designed ‘crop circles’ at the bottom of the ocean as part of an elaborate mating ritual.
The behavior was first documented by a photographer named Yoji Ookata who later returned with a film crew from the Japanese nature show NHK which later aired an episode about the fish. Take a look.
