Alien Archive 3 kind of has this with an “aliens by terrain” index. Listed creatures are:
aspecna (spectra), blinking telelith, Drift architect (Drift native), driftdead, driftdead amalgam, iridia (spectra), paraforan, paraforan fragment, swarming telelith, time eater (Drift native)
Garaggakals are also mentioned to be native to the Drift. And just about anything can show up there by accident.
