What are Planarians flukes tapeworms?
Similarly, what is the difference between planarians and tapeworms?
The key difference between planarians and tapeworms is that planarians are unsegmented free-living flatworms of the class turbellaria that live on freshwater. Meanwhile, tapeworms are segmented parasitic flatworms of the class Cestoda which reside on the intestines of animals including humans.
Beside above, what does it mean that many flatworms are parasites? Flatworm, also called platyhelminth, any of the phylum Platyhelminthes, a group of soft-bodied, usually much flattened invertebrates. A number of flatworm species are free-living, but about 80 percent of all flatworms are parasitic—i.e., living on or in another organism and securing nourishment from it.
Just so, what type of gut do flatworms have?
Because they don't have a body cavity, flatworms are considered acoelomates. They have simple digestive systems, with mouths to take in food and long digestive tracts to diffuse it around the body. Most flatworms take in food via their mouth, then move it into a digestive gut that attaches to the digestive structures.
Do Tapeworms have eyespots?
Flatworms have no true body cavity, but they do have bilateral symmetry. Due to the lack of a body cavity,flatworms are known as acoelomates. Flatworms have an incomplete digestive system. Most flatworms have a distinct head region that includes nerve cells and sensory organs, such as eyespots.
