Marsh Cleaner

After the gamma ray disaster the Flisch marsh was almost lifeless, only inhabited by the marshrub. As time passed by the water got filled with nutrients and broken parts of shrub and the ecosystem held great potential for new hosts; ciliognathuses in the nearby river that were swept to the marsh started inhabiting it. They have adapted to their new surroundings by evolving and feeding solely on the shrub particles in the water and other biological nutrients that sunk in the marsh. Later they also spread back to the river, which they came from, and the nearby lakes.

They have also evolved a better set of feeding hairs in order to grab the particles from the water and two reproduction organs which they use for an improved version of the conjunction which could be referred as sexual reproduction in almost any way as all the four daughter cells share both their parents DNA; still there are no different sexes and every cell can reproduce with any other cell. This form of reproduction became even more common than the binary fission in areas where the cell had better conditions and less competition like the Flisch marsh.
