Aquatic Animals that eats cells

I guess it depends on how close you are to becoming multicellular. I’ll again bring up the fact that a single editor cycle is 100 million years in the microbe stage, but the time gets shorter as you advance. So meaning that that huge species is going to entirely evolve into an “intelligent” species that’s going to pollute and/or destroy the planet. So that’s why the player needs to keep up with the AI species or otherwise the game needs to be considered over.
