They are acoelomates and have no specialized circulatory and respiratory organs, which restricts them to having flattened shapes that allow oxygen and nutrients to pass through their bodies by diffusion. Planaria, liver fluke, and Taenia all are flat worms.

Liver flukes are an example of a parasitic flatworm. View the preserved tapeworm and the slides of the tapeworm scolex (head) and proglottids ( reproductive

Free-living flatworms like the planaria are grouped into the Class Turbellaria. The most common species studied in the lab is the brown planaria, Dugesia. Like flukes and planarians, tapeworms are hermaphrodites. However, they are capable of self- fertilization. The head region of the tapeworm is called the solex and it contains hooks and suckers for attaching to a host.

The larval intermediate of another tapeworm of canids, Echinococcus granulosus , also may form hydatid cysts, particularly in liver and lungs. Not all cases are diagnosed because these flukes can be asymptomatic, meaning, they live 25-30 years (or up to 50 years) within your liver, bile ducts or pancreatic ducts and you may never know it. They are often acquired through ingesting fresh water cress, fresh water fish that is raw, pickled, smoked or dried. Students will use whole mount prepared slides of the tapeworm and liver fluke. (Note: These can be purchased through any biological supply house.) They will observe these microscopically and compare them with the planaria. Remind students that both the tapeworm and the liver fluke are parasitic organisms.

The flatworms, flat worms, Platyhelminthes, or platyhelminths are a phylum of relatively simple Cestodes (tapeworms) and trematodes (flukes) have complex life-cycles, with mature stages that Two planarian species have been used s Planaria, liver fluke and taenia solium are [CPMT 1983; CBSE PMT 1993] For completing its life cycle, Tapeworm requires/ Intermediate host of Tapeworm is This phylum also contains parasitic flatworms, like the tapeworm and the liver fluke.

The ‘bladder worms’ typically affect the liver or peritoneal cavity and are caused by the larval form (metacestode) of Taenia hydatigena, the common tapeworm of the dog family. The larval intermediate of another tapeworm of canids, Echinococcus granulosus , also may form hydatid cysts, particularly in liver and lungs.
