Zero-G Atraxid
Source Secrets of the Swarm pg. 109
You feel perfectly at home where there's no gravity. Atraxids were early adopters of space flight among the Szandite Collective, and many atraxids took to it readily, thriving in a zero-g environment. You do not gain the clumsy and off-guard conditions due to being untethered in zero gravity, though you can still gain those conditions due to other effects.
