User blog comment:BlueFrackle/Alternative Forms of Life/@comment-160529-20130511150543

the reason I am against "Species with Unknown Biochemistry" is because I generally dont like categories with more than three words, when a simpler two word title can mean the same thing.

and the reason I favor "irregular lifeforms" over others is because while still somewhat anthropocentric, the average alien creature throughout fiction is somewhat understandable.

This would be a rare instance of "out-of-universe" categorization, saying they are irregular or. . . not normal compared to other aliens in fiction, rather than their own universe.

I dont like having out-of-universe perspective categories, but sometimes it is needed.
