Yes, they do. They have true coeloms, i.e. their coeloms (body cavities) are lined with mesodermal (referring to the embryonic germ layer which forms the muscles, nervous system, and generally the "meat" of the body") cells forming its inner lining.

What phylum of worms has a true coelom and a complete digestive tract?
Annelida
What kind of animals are acoelmates?
Acoelomates is the name given to animaks which lack a coelom. Coelom is true body cavity which is formed in mesoderm by different methods e.g. schizocoelous or enterocoelous.Coelom is lined by mesodermal epithelium . Phylum Platyhelminthis is included in acoelomates. Pseudocoelomates possess a pseudocoelom while coelomates possess a true coelom.
What phylum have true coelom and are deuterostomes?
chordata
What type of coelom does an enterocoelous animal have?
A coelomate animal is the one which has a body cavity in which well developed organs can be accomodated.
Five characteristics shared by all worms?
biologist classify worms into three major phyla-flatworms roundworms and segmented wormsYes, that is true, but those are not characteristics! Some of their characteristics are:-A knot of nerve tissue-Sense organs-Sexual reproduction-Bilateral symmetry-Obtaining food by sucking their hostsGood luck!!!! I know science can be challenging at times!!!!!! :D
What characteristics of a segmented worm make it a worm?
Annelids are bilaterally symmetric and triploblastic protostomes with a coelom, closed circulatory system and true segmentation. Their segmented bodies and coelom have given them evolutionary advantages over other worms.
Do mollusks have a pseudocoelom?
No, mollusks have a true coelom instead of a pseudocoelom. The coelom is a part of mollusks and annelids that is a cavity within the mesoderm that is filled with fluid.
Does pseudocoelom has same functions as a true coelom?
Yes, they have the same function; they are different only in they way they formed
How are earthworms and ascaris similar?
Annelids are segmented whereas roundworms are not. Annelids have a true coelom while roundworms have a pseudocoelom. Annelids have a more complex nervous system than roundworms. Annelids have a more complex circulatory system than roundworms.
Is tape worms segmented worms?
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.
Is it true earthworms are segmented worms?
Yes
Is it true that tapeworms are parasitic segmented worms?
Yes, that is true.

Do flatworms have no coelom a pseudocoelom or a true coleom?
no
Do roundworms have no coelom a pseudocelom or a true coelom?
Coelom. It is partitioned by septa, which is a divider between segments of the worm.
Do cnideria have a coelom?
yes it do hav a true body cayity or a coelom.
