Torquigener albomaculosus occultarum
This particular fish was first ‘discovered’ in 2013, off of the coast of Japan. Sort of. In boring, mundane terms it’s a species of pufferfish whose males attract mates by drawing remarkably symmetrical and elaborate patterns in the sand. Torquigener albomaculosus occultarum will even decorate the pattern with pieces of shell and seafloor debris; it is presumed that all of this is due to the usual blind, aimless iterations of the evolutionary process.
