Flatworms are considered acoelomate, since they have no body cavity, and roundworms are pseudocoelomate because they have a body cavity, but it is not derived from the splitting of the mesoderm tissue. Also, flatworms only have one opening in their digestive system unlike roundworms with two.
Flatworms and Roundworms have bilateral symmetry as a body type.
they have an open body cavity.
It lacks body cavity .
Pisces or fish have true internal body cavity.
Roundworms are classified in the phylum Nematoda. They have this name because of their cylinderical body shape. They have a pseudocoelom for the body cavity. Some are parasites (Ascaris), some are useful in biology research (C. elegans). They are found almost everywhere!

What type of roundworms do you mean? roundworms in general and kind
The type of body cavity shared by all mollusks is pseudocoelom is a false statement. The correct answer is coelom.
Yes. However, this is not a true coelom. Roundworms are pseudocoelomates -- their mesoderm lines the endoderm and ectoderm, but there is no connection between the two. Therefore, it does not satisfy the definition of a coelom. However, since there is a body cavity still, this animal is said to be a pseudocoelomate.
A bilateral animal has a lined gut cavity. On the other hand, animals like roundworms have a gut cavity but it is only partially lined.
Roundworms can cause serious damage to humans and other living things. Roundworms also live in pigs, so when people eat it pork undercooked, they can have roundworms inside their body, where it causes a disease. Earthworms cannot do any of these things that roundworms can do. (Roundworms are parasites, so if you don't want to have parasites inside your body organs, DON'T EAT UNDERCOOKED PORK OR ANY TYPE OF MEAT)
They don't have bodies!
Jellyfish are bell shaped and roundworms aren't. Jellyfish sting and roundworms do not. jellyfish are radial and and roundworms are not.
Acoelomate animals, for example, flatworms, do not have a body cavity. Their organs are held in place by mesodermal tissues that are semi-solid.
