Use a preserved specimen or an (anesthetized) live one for dissection. Each annulus (ring) marks one somite. The tip of the worm anterior to the mouth is the prostomium. The next segment is the first somite. The last somite bears the anus. Some somites at the anterior of the worm are swollen, forming a glandular area, the clitellum. ................
