The life cycle of Earthworms belong to this phylum. Each Planaria, liver fluke and taenia solium do not have a true coelom. Hence they do not have segmented body. Segmented body is a characteristic feature of phylum annelida and phylum arthropoda. Corals belong to the phylum (a) Protozoa flatworm, dugesia.
2. The hooks attach themselves to the inside of the intestines by hooking in, and the suckers attach themselves to the intestine by suctioning itself to it. 3. Planaria- has eyes, auricle, class Turbellaria, lives in fresh water. Tapeworm, liver fluke and planarian belong to the p hylum Platyhelminthes. The most important and a common characteristic of all organisms belonging to this phylum is that their bodies are dorso-ventally flattened. The bodies of the organisms belonging to this phylum are flat since they do not have a body cavity and are acoelomate.

They are acoelomate, triploblastic, bilaterally symmetrical and unsegmented.

Most Platyhelminthes are parasites on other animals, only the Turbellarians are mostly non-parasitic. Phylum - Platyhelminthes (Flatworms) The flatworms include more than 13,000 species of free-living and parasitic species. There are 3 classes of flatworms, the planarians, flukes and tapeworms. General Physical Traits (Anatomy): Flatworms are bilaterally symmetrical. Phylum Platyhelminthes The flatworms include more than 13,000 species of free-living and parasitic species. There are 3 classes of flat-worms, the planarians, flukes and tapeworms.

Next, these worms have tissues that are organs. Introduction to the Platyhelminthes Life in two dimensions. . .
The flatworms are acoelomate organisms that include many free-living and parasitic forms. The flatworms possess neither a lophophore nor trochophore larvae, although the larvae of one group of flatworms, the Polycladida (named after its many-branched digestive tract), are considered to be homologous to trochophore larvae.

Cestodes (tapeworms) and Trematodes (flukes) are two Classes of the Phylum Platyhelminthes. The adult tapeworm has no digestive tract but absorbs its nourishment through its body surface. The head or scolex of the worm is provided with means of attachment to the intestinal wall of the host. Figure 19.11. Life cycle of the human liver fluke, Clonorchis sinensis.
