ANNELID
Annelid
The annelids, formally called Annelida, are a large phylum of segmented worms, with over 2,000 modern species including ragworms, earthworms and leeches. They are found in marine environments from tidal zones to hydrothermal vents, in freshwater, and in moist terrestrial environments.They are bilaterally symmetrical, triploblastic, coelomate organisms.They have parapodia for locomotion. Although most textbooks still use the traditional division into polychaetes, oligochaetes and leech-like species, research since 1997 has radically changed this scheme, viewing leeches as a sub-group of oligochaetes and oligochaetes as a sub-group of polychaetes.The above text is a snippet from Wikipedia: Annelid
