Segmented worms are bilaterally symmetrical. Their body consists of a head region, a tail region and a middle region of numerous repeated segments. Each segment is separate from the others by a structure called a septa.
1 Segmented worms are coelomate-they have a true coelom which forms within the mesoderm. 2  Most worms have sense receptors and nerves concentrated at their anterior end. 3  This is known as cephalization. 4  Some worms show a great ability to regenerate lost or injured parts, others do not.
