Changes

'''Species 8472''' are also able to withstand the vacuum of space; It is probable that in their natural Fluidic Space, they are able to swim through the organic matter. As far as Starfleet can tell, their space is similar to their ships, and share their unique physiology. They have been observed to have as many as five different sexes, each of which occupies a different region of their Fluidic Apace Space realm. It is not known if Species 8472 is the only species to have evolved in Fluidic Space, or if they exterminated the others as they attempted to do in normal space.
