unless we compare it to other species here. . . or other species within the universe.

Take star trek for example, they have a fine line between what is normal and what is abnormal. With star trek it is easy to see what an "alternative form of life" would mean in the context fo the franchise.

as there is a large sample-size fo species to provide context. . . for what is typical in the universe.

we just need to increase the sample size to all fiction, and any form of life that falls far outside the norm would fit what this category would be. Hence by idea of "irregular" or "nonstandard". . . heck maybe even "nonconformative" would work (although I dont know if that is an actual word)

wait. . . how about "Unconventional Lifeforms" that seems to get the point across from every perspective that I can imagine here.

life forms that do not follow conventions. . .and while anthopocentric somewhat. . . its not so much
