Classification of Phylum Annelida

Phylum Annelida is divided into four main classes, primarly on the basis of setae, parapodia, metameres and other morphological features

The active polychaetes utilize parapodia for gas exchange. Each parapodium is divided into an upper and a lower section; it is the upper section that serves a respiratory function. Muscles and locomotion: Annelids have two sets of muscles that are used to contract and elongate the body.
