Want this question answered?
A cnidarian has an incomplete gut with just one opening. BTW Those who said that "How many openings does cnidaria have?" and "How many opening does an earthworm have" are the same question are idiots. An earthworm in an annelid, or a member of phylum Annelida. Cnidarians are in an entirely different and less developed phylum, that is, phylum Cnidaria. So there. STAY IN SCHOOL!
Michrochaetus rappi (Michrochaetus michrochaetus)
setae
Distinguishing characteristics of the phylum annelida are conspicuous metameric segmentation, they are triploblastic, coelomate, bilaterally symmetrical, tubular bodies (worms), they have a nervous system and some sense organs
annelid arthropod cnidarian echinoderm flatworm mollusk
gopigos islands
they all have different shaped bodies and different characteristics
Earthworms are a worm but flatworm is a type of heart worm
this is because all of them have segmented body ,they are billaterally symmetrical , they also have a ceolomated body

Cestoda is the actual classification of a tapeworm.
ough. tapeworms and annelid are worms, leeches are not in the worm family. Leeches and earthworms are annelid worms. The name comes from the "ring"-like body segments. Leeches may not look like worms but they definitely are. Tapeworms are members of the flatworms (phylum Platyhelminthes).

fish have a bladder and a stomach. worms have a crop, gizzard, and intestine.
Annelid is just the Phylum. There are actually 17,000 different species in this one phylum! Three different worms could be: The Tape Worm, The Segmented Worm, and the Christmas Tree Worm.
they have longitudinal and circular muscles (to move), a coelom, a well developed digestive system, 5 aeortic arches (like 5 hearts), a clitellum (part of the reproductive system) and ..... thats all i can think of. Sorry! . :)
Annelid Worms use Coelomic Fluid
