Whereas flukes are flattened and generally leaf-shaped, adult tapeworms are flattened, elongated, and consist of segments called proglottids. The terminal segments are gravid, with the egg-filled uterus as the most prominent feature. The scolex contains the cephalic ganglion, or “brain,” of the tapeworm nervous system.

Liver Flukes. View the preserved liver fluke specimens. Liver flukes are an example of a parasitic flatworm. Access this website to learn more about the liver fluke life cycle.

The elongated body contains several segments called proglottids. The mostly free-living Turbellaria include the planarian, Dugesia, shown above; these are found in the oceans, in fresh water, and in moist terrestrial habitats, and a few are parasitic. The Trematoda, or flukes, are all parasitic, and have complex life cycles specialized for parasitism in animal tissues. The common sheep liver fluke, Distomum hepaticum or Fasciola hepaticum has the dwarf pond snail as its intermediate host, and is another common trematode. The adult fluke lives in the bile passage in the liver of sheep, other ruminants, or even man. The eggs are passed with the faeces. After hatching it enters the snail.

Planaria, liver fluke, and Taenia all are flat worms. Platyhelminthes: Planaria, Flukes, and Tapeworms. STUDY.

Both flukes and tapeworms are human parasites which cause digestive system related complications upon infection. They are administered to the body via consumption of contaminated food and raw meat. Flukes and tapeworms differ in their shape where the flukes have a leaf-shaped structure, and tapeworms exist as elongated flat structures.
