Summary Introduction
Introduction:
All the animals, considered as annelids, contain segmentation in their body. The segments are ringlike that are separated by septa in the body of annelids. These segments involve a pair of excretory organs, a ganglion and a set of reproductive organs (marine annelids). Annelids contain anterior and posterior segments that are light, chemo and a touch receptor. Each segment is connected through a ventral nerve.
