Phylum Annelida Characteristics They are mostly aquatic; marine or freshwater some terrestrial, burrowing or tubicolous, sedentary or free-living, some commensal and parasitic. The body is elongated, triploblastic, bilaterally symmetrical, truly coelomate and vermiform. Annelids have a bilateral symmetry. Some have line segments to show each body part, and also have a ''bandage'' called the clitellum which is close to the worm's head. The worm's head doesn't have eyes, nose, or ears, but a mouth structured for its specific environment. Earthworms have a simple mouth to chew up dirt, roots, and leaves. Giant tube worms have a plume (feather) to filer out Characteristics of Annelida: Bilaterally symmetrical and vermiform.
