Comment on Askewbugs of planet Ullr by Preradkor
Hmmm Wow yeah! I really didn't think of snails, even though they're asymetric! 
I't mainly due to their shell, though, slugs are far more "regular" in terms of symetry...
Thank you for the inspiration, but I don't think I'll manage to create "bugs" with segments like that, I think that would be copying you, so I'll probably have to think up some other way how to make things look different...
I was somehow thinking of making worms with this kind of segmentation, or something like chitons, but probably not "arthropods"
For "arthropods" I had a different idea, I was thinking more along the lines that the individual "segments" are separate animals (four-legged) and that there are two groups of these critters, some living alone (For those, I imagined something along the lines of something small and primarly aquatic, but then I started to think that something tick- or mite-like and parasitic would work too. The other group would consist of colonies composed of those "segment-critters" which will be so used to living together that they'll act like a single animal, but I still have no idea how they would molt or reproduce... I was thinking that they could "let go" some of the segments, which would wander off, find a segment from another colony ad mate, but I don't know how that would work... =/

Tapeworms are actually long chains of tiny cylindrical flatworms. The "head" is actually the rear end of the chain and new segments sprout from there.
really? O.o
Let me look it up... okay, the "head" is where the segments spawn from and attaches inside the stomach. It does control the rest of the tapeworm, with a nerve center inside, and it is responsible for absorbing food. The segments form a "tape" which trails into the digestive system of the host, and each has its own reproductive system and some other organs. By the time it reaches the end of the line, so to speak, a segment is nothing more than a bunch of eggs that can be passed on to another host.
yeah, I know how a tapeworm works, I just found your definition of it as a "link of flatworms" intriguing... 
I must say that these compound arthropods from your idea sounds really bizzare and alien. But I think that better (to make them even more alien) if separate creatures would be fused not exacly like typical segments in earth arthopods, but rather something between helical and vinegrape cluster. That kind of organism would certianly have very strong tendency to specialisation of creatures in whole colony (like cells in multicellular organisms). Some creatures will provide propulsion, some will chew food for others, some will have limbs or horns used to protect colony (or hunt) and some would control behaviour of the others, likie some kind ow whole organism brain.
On earth there are also organisms of that kind, for example portuguese man o'war, but they are all simple creatures with no brain and limbs. Arthropods on earth form colonies in totally different way.
Breeding of these creatures should be simmilar to breeding of ants or termites. Inside of the colony should be just a queen creature (or queen organ) which is mother to rest of colony body. When colony breeds it should just relase young queens. It is the simplest possible way of breeding advanced colonies of this type. Of course it can be complicated to be more simmilar to growing not ant colony bugs but the multicellular organism.
I just remember in one Jacek Dukaj short polish science fiction story "In partibus infidelium" appears alien sentient race known as Crickets, what are based on something between portuguese man o'war and insect colony. But description of them is very limited, they were not the main theme of story. But creatures you described would probably evolve in this direction.

Hmmmm... Your idea is very interesting! Though I think it'll need a while to sink in, before I can visualize it properly... I know about the man-o-war, and that was actually the inspiration for making colonial animals. I'll see what I can come up with, thank you for your time and idea! I'll let you know what I can come up with!

I'll let you know!
