The spirobast split from its ancestor and spread to the plains. Like the luminuseven, it will swim toward the light source, remaining mostly in the water surface. It lost its flagella in exchange of a slim coiled shape surrounded by three rows of cilia, allowing it to form large groups of entangled spirobasts. Due to abundance of light in the equatorial region, this species can reproduce quickly, being also found in water puddles in the plains.
