The head and the rear of the body is not segmented. The digestive system of species in this phylum runs the length of the body. Food is taken in at one end of the body and expelled at the other end. Annelids have two sets of muscles that help them move.he head and the rear of the body is not segmented. The digestive system of species in this phylum runs the length of the body.

Annelids are considered members of the Lophotrochozoa, a super-phylum of protostomes that also includes molluscs, brachiopods, flatworms and nemerteans. The basic annelid form consists of multiple segments. Each segment has the same sets of organs and, in most polychates, has a pair of parapodia that many species use for locomotion. Septa separate the segments of many species, but are poorly defined or absent in others, and Echiura and Sipuncula show no obvious signs of segmentation.
