The annelids (Annelida, from Latin anellus, little ring), also known as the ringed worms or segmented worms, are a large phylum, with over 17,000 extant species including ragworms, earthworms, and leeches.he annelids are bilaterally symmetrical, triploblastic, coelomate, invertebrate organisms. They also have parapodia for locomotion. Most textbooks still use the traditional division into polychaetes (almost all marine), oligochaetes (which include earthworms) and leech-like species.

Worms are invertebrates with long, soft bodies and no hard skeleton. Their shapes are varied, and they range in size from microscopic to 75 feet in length. Scientists have classified worms into more than 15 phyla. The phylum Annelida contains the segmented worms. Annelida is further divided into three subclasses: Oligochaeta, Hirudinea and Polychaeta. Thousands of species of segmented worms comprise these three subclasses.
