So the key to the question was that your worm is segmented. Marine worms are found in several different phyla, including the Platyhelminthes, Nematoda, Annelida (segmented worms), Chaetognatha, Hemichordata, and Phoronida. Accordingly, an earthworm is a round and cylindrical shaped worm, which survives under ground in the soil. A. the Cnidaria (Hydra, etc.) What is different about each group of organisms that requires us to classify them into multiple phyla? Annelida do not include the smooth worms that come to mind when we think of them, but also bristled ones, too. 17. Biology deals with many kinds of worms. 2. include leeches, earthworms, and polychaete worms : have characteristically long bodies with both internal and external segmentation : use their coeloms as hydrostatic skeletons : have a mouth that is separate from the anus. Would you like to merge this question into it? However, the features listed above provide a way of categorizing animal phyla in terms of their body plans. A. soft-bodied worm with a gastrovascular cavity B segmented worm with a cuticle and a complete digestive tract C … Traits: Platyhelminthes are multicellular.
