Monolith Radiocoon

There is a lot of flora inhabiting space, though, not very many decomposers, which allowed some Armored Radiocoons to evolve in a very strange way, opening up the bottom of their cocoon, and taking on a cylindrical shape. Monolith Radiocoons are like the fungi of space, and have completely dropped their juvenile stage, being born straight into the cocoon stage, and tend to grow on surfaces. They start out sessile, rooted into whatever surface they were born on, seeping away nutrients from it, be it organic or inorganic, while also consuming radiation and spite as a renewable resource. After a certain point, they are able to retract their roots and sort of swim to other spots with better sources of nutrition, and may grow very large if they find a good enough spot. Strangely, they have permanent holes in their cocoon with eyes poking out, allowing them to see outside of their cocoon, and use a sort of immune system to keep things out. They are able to re-insert their roots into other things once settled, and will continue to use them to extract nutrients. Their soft underside is exposed while swimming, so spikes jet out from under the cocoon in the area until they find a spot to settle. Since they have permanent holes in their cocoon, they do not have to tear it open to release their spores.
