Apparently, "Arms" used to indicate that an inn, pub, hotel, etc. has a coat of arms on their sign, to indicate that they had some kind of noble patron. I imagine this is not true of all places with that in the name (especially in America), as they may just be trying to sound fancy.
Spiral arms come in different "flavors": 10% grand-design (two well-defined spiral arms) 60% multiple-arm, 30% flocculent spirals (no well-defined arms at all). Spiral arms seem to be trailing arms, but this is very hard to determine. In some rare cases, spiral arms may lead.

There are essentially 8 types of invertebrates. They may be named as Annelids, insects, mollusks, protozoa, echinoderms, crustaceans and arachnids
The major difference between echinoderms and other invertebrates is that there are few examples echinoderms that do not live in ocean water and none live on land. There are examples of other invertebrates that live in both fresh and salt water and on land. Echinoderms also display radial symmetry as do the jellyfish and sea anemones. If you want to tag the one thing that echinoderms have that no other living invertebrate has, you would probably have to point to their water vascular system (see link).
