'Nashville' Season 3 Will Start This Fall But Here's a Spoiler-y Preview To Tide You Over. Nashville fans, we can all relax. ABC's Nashville will return for a third season this fall. And not only will the series be back, it will keep its Wednesday night time slot where it will battle returning shows and some newbies.

Annelid, phylum name Annelida, also called segmented worm, any member of a phylum of invertebrate animals that are characterized by the possession of a body cavity (or coelom), movable bristles (or setae), and a body divided into segments by transverse rings, or annulations, from which they take their name.
The Annelida and Arthropoda phyla share membership in the broader Animalia category, or kingdom, that includes all animals. From that similarity, however, they go in separate directions. Arthropods and annelids are different types of organisms.The Annelida phylum includes most worms, while the diverse Arthropoda phylum counts arachnids, lobsters and insects among its members.ne difference between Annelid and Arthropod phyla is their diversity. The Annelid phylum contains three classes of organisms: Polychaeta, Oligochaeta and Hirudinea. The first two classes consist of worms differentiated primarily by the use of parapodia for movement; the third includes leeches.
