Anatomically Correct: Space Plankton
+0
−1
This creature was void-born in the farthest depths of time in this Universe. Drawing its energy from electromagnetic radiation, and sealed against the vacuum of space, this drifting creature establishes itself in stable orbits, Lagrangian points, and in the wakes of comets. With the patience of a microbe, it can be ejected from solar systems and wait millions of years to re-establish itself. So, by fortune, it has spread, over billions of years, across this galaxy and beyond.
How does space plankton work?
It must:
- Be able to survive and reproduce in the vacuum of space.
- Generate energy somehow using electromagnetic radiation. It would be cool if multiple strains could utilize different frequencies.
- Go dormant as necessary to survive millennia or more in slow, sublight travel across galaxies. Upon reaching a suitable new habitat, it must be able to reproduce and grow once more.
