They can also be nonexistant, especially in organisms that can become roughly radially symmetric in 2 axes.

No. The fact that the real equivalents of the lower structure have no organs, and how lower organs would mean more muscle mass and more tissue, negate the idea of lower organs. Disgustedorite wrote: In fact, your illustration completely ignores the arms. Where do they attach? They need to attach to something solid or they will be torn right off with ease. Your illustration is, by your own logic, completely negated by this problem, and therefore by your own logic you are completely and totally wrong about everything regarding the anatomy of the bird blob. Why would a creature with the entire body being non-solid, need solid shoulders?

So, just because a flatworm can crawl about on land a bit, that means that a space pterosaur doesn't need organs at all???
