FYI here are the species i added as minor species:
Beige Goo Insane nanite swarm
Cynos Walking plants sustained by a giant non-sentient mother plant
Derthrean Pacifistic, bioengineering, pain-ridden, floating plant/virus synthesis
Etty cybernetic plants
Fifty-seven Math-obsessed sky-serpents
George A single, childish Telelpathic entity that consists of tons of centipedeoids
Gis Guf G'thrim Shelled herbivores that live off a singular planets-sized colonial gel.
Kobuntura Sentient magnetic dust formations with a fascination for building and construction.
Laenfa Sneaky, telepathic, sentient vines
Nnymnmn Planet-wide waveforms in the magnetic field of a planet (subconsciously, i made this too similar to the Kobuntura-- will be adjusted)
Phinnert Flying Monkeys
Setinon individualistic sentient microscopic cells
Silexians Gleaming gardener robots, left on their own
Sslith Flat, aquatic, plyable creatures
T'aeghirus Weak, flightless birds, united in total mutual cooperation
Trenchers Enigmatic wheeled robots
Ugmorrs Lava-dwelling yeast piles, which form temporary golems
Again, it doesn't mean these will be permanently minor, but i thought it would be more fun for everyone else if i mostly filled the ranks with familiar species, than use up the very small pool of species that make sense as planet-bound, and then make up a bunch of totally new ones. I will be adding or describing more new species like the fifty-seven designed from the ground up to be planet-bound.
