The Infrakingdom Coelomopora is a member of the Branch Deuterostomia. Here is the complete "parentage" of Coelomopora:

The Infrakingdom Coelomopora is further organized into finer groupings including:

Phyla

Echinodermata

Echinoderms (Phylum Echinodermata) are a of marine animals. Echinoderms are found at every ocean depth, from the intertidal zone to the abyssal zone. Aside from the problematic Arkarua, the first definitive members of the phylum appeared near the start of the Cambrian period [more]

Hemichordata

Hemichordata is a of worm-shaped marine deuterostome animals, generally considered the sister group of the echinoderms. They date back to the Lower or Middle Cambrian and include an important class of fossils called graptolites, most of which became extinct in the Carboniferous. They seem to have a primitive form of notochord, formed from a diverticulum of the foregut called a stomochord, but this is most likely the result of convergent evolution rather than homology with the vertebrate notochord. A hollow neural tube exists among some species (at least in early life), probably a primitive trait they share with the common ancestor of chordata and the rest of the deuterostomes. [more]

At least 576 species and subspecies belong to the Phylum Hemichordata.
