Grunion lay their eggs. The male then wraps himself around the female to deposit his sperm, and for the next 10 days the grunion eggs remain hidden in the sand. At the next set of high tides, the eggs hatch and the young grunion are washed out to sea. A related species, the false grunion ("Colpichthys regis") lives in the Gulf of California. Although the fish looks and acts similarly, it does not have the same breeding method. The currently recognized species in this genus are: Grunion were originally classified as part of the Atherinidae family of silversides, but are now
3D Virtual Creature Evolution (from zero, as not having an influence on fitness, to one, or having maximum influence) to determine the fitness goal. What generations the fitness function applies to can also be set. The environment, or “Terrain”, is then determined. This includes a flat plain, bumpy terrain (in which a hill is generated around creature that constantly inclines as distance is traveled from the creature’s spawning point), water (a low gravity simulator, non-functional), and “spheres” (spheres are generated above creature to catch). Everything in the simulation is viewed from a first person viewpoint. After settings are determined, the first generation is generated
