The body cavity of these usually small to microscopic, worm-shaped animals is a pseudocoelom, and they lack a circulatory system.
A systematic list of the phyla of the animal superphylum Deuterostomia (deuterostomes)...

Maybe we could just leave it like that.
I’m gonna study some phylums (porifera, mastigophora, chordata, cnidaria, superphylum arthropoda, annelida, platyhelminthes etc.) for Zoology!
As for my answer, you need not to know.

  Journal of Systematic Biology--Volume 8, Issue 1
There is some disagreement with the classification of the phylum Ectoprocta as to whether they belong with the Pseudocoelomates, Proterostomes or in a superphylum of their own.
The tree length is 59 as compared to the statistical minimum of 28 and the maximum of 130.
The Superphylum Ectoprocta is separate from Pseudocoelomates, Proterostomes, and Lophophorates.

 Chordate - Wikipedia, the free encyclopedia
In all vertebrates except for Hagfish, the dorsal hollow nerve cord has been surrounded with cartilaginous or bony vertebrae and the notochord generally reduced.
The chordates and two sister phyla, the hemichordates and the echinoderms, make up the deuterostomes, a superphylum.
It has been theorized that the phylum originated as a result of paedomorphy occurring in a primitive ancestral form.

 Brachiopod - Wikipedia, the free encyclopedia
The phylum most closely related to Brachiopoda is probably the small phylum Phoronida (known as "horseshoe worms").
Along with the Bryozoa and possibly the Entoprocta/Kamptozoa, these phyla constitute the informal superphylum Lophophorata.
The inarticulate brachiopod genus Lingula has the distinction of being the oldest, relatively evolutionarily unchanged animal known.

We performed a cladistic analysis of 20 characters to determine whether the Superphylum Arthropoda is monophyletic or polyphyletic.
We determined that there are significant differences within the Superphylum Arthropoda to warrant its division into three individual phyla.
Current phylogenetic research suggests the division of the Superphylum Arthropoda into 3 separate phyla: the Uniramia, the Crustacea, and the Chelicerata (Holt, 2000; Margulis and Schwartz, 1998; Manton, 1979).

These groups are all grouped into the superphylum of Lophophorate because of their lophophore, the fan of cilia around their mouths.
There is even some debate over whether some of the phyla that are grouped under the superphylum Lophophorate are paraphyletic.
pterobranchs, that some scientists feel should be included in the superphylum because of similar structures (Halanych 1993).

Recall (but don't memorize) the classification hierarchy: (i.e., know that a superphylum is more inclusive than a phylum, and that a genus is less inclusive than a family, etc.)
Know the general body plans of acoelomate, pseudocoelomate and coelomate animals (as shown in the diagram in lecture).
Know the general progression of complexity of the major animal groups as shown in the phylogenetic tree.

These phyla have been under debate for many years as to whether they should be placed as deuterostomes, protostomes, or as intermediates between the two.
Saito et al (2000) claim that the study of the COI amino acid sequences is an accurate way to determine relationships between organisms because they are highly conserved throughout time.
The result shows the Lophophorates are actually sisters to the Protostomes and Deuterostomes and are a separate Superphylum.

 superphylum Chelonia
For example, I could argue (contra Friesen's claim, which is exactly what set me off in the first place) that turtles HAVE gone through a profound adaptive breakthrough, namely, evolving a true shell and figuring out how to get their pectoral and pelvic girdles INSIDE their ribs.
If this Houdini-esque kind of a trick isn't "profound," I don't know what is. It seems to me that I could argue for turtles not only being a "class" of their own, but, say, a "subphylum" or a "phylum" or even a "superphylum"!
Systematists can't even make their minds up about what "rank" the Arthropoda should have, so what's to stop me, apart from YOUR personal opinion?

 Arthropods at the Cofrin Center for Biodiversity
The classification system used here (Margulis and Schwartz 1998) recognizes three distantly related phyla, now grouped into a Superphylum Arthropoda.
The superphylum Arthropoda can be divided into three sub-groups called phyla.
Members of the phylum Chelicerata have mouthparts called chelicerae, which are either fang-like or pincer-like in form.

Arthropoda (actually perhaps better classified as a “superphylum” containing at least four phyla)
The arthropods may actually be divided into four separate (though related) phyla all contained within a “superphylum” called Arthropoda:

 Deuterostomia   (Site not responding. Last check: 2007-09-17)
I've seen it placed as a superphylum of the subkingdom Bilateria, but more often as an unranked group.--Josh Grosse :I think you're right.
I've never heard them called a subkingdom and my General bio text doesn't say anything about placement.
Although I do remember other instructors of mine say that they are a type of superphylum since several Deuterostomia phyla all have similar zygote cleavage.
