Torquigener albomaculosus


Scientists recently solved a 20-year-old mystery under the sea and discovered a new fish. Intricate ‘crop circles’ with geometric designs about six feet (2 meters) in diameter were found on the seafloor off the coast of Amami-Ōshima Island. They turn out to be the work of this new species of pufferfish. Males construct these circles as spawning nests by swimming and wriggling in the seafloor sand

The nests, used only once, are made to attract females. The nests have double edges and radiating troughs in a spoke-like geometry. The design isn’t just for show. Scientists discovered the ridges and grooves of the circle serve to minimise ocean current at the centre of the nest. This protects the eggs from the turbulent waters and possibly predators too
