Tiny Swarmer

The tiny swarmer has replaced its ancestor the green swarmer. It has shrunk to half its ancestors size and has spread across the equator of Sagan 4's oceans. They live much like other swarmers filter-feeding on the surface and absorbing sunlight with its photosynthetic skin. They are an important part of the marine ecosystem. They can spawn year around and are only limited by the abundance of microbes they eat and the sunlight they absorb.
