For example, Funch and Kristensen state that the new creature most nearly resembles the phyla Ectoprocta and Entoprocta
. Yet scientists fail to agree that Ectoprocta and Entoprocta
are closely related, Morris notes.

IYC and PCP were examined for two hours by 17 people including specialists in Annelida Polychaeta, Ascidiacea, Bryozoa, Cnidaria, Crustacea Cirripedia, Entoprocta
and Mollusca that defined the taxonomical scope of the survey.
Although adult morphology varies vastly across the group, many core Lophotrochozoa (including the Mollusca, Annelida [including Vestimentifera, Pogonophora, and Echiura, and possibly Myzostoma, and Sipunculida], Gnathostomulida, Nemertea, dicyemid Mesozoa, Entoprocta
, and some Platyhelminthes [including polyclad Turbellaria, Catenulida, and Macrostomida]) exhibit spiral cleavage, a highly conserved pattern of early development.
On the fine structure of the creeping larva of Loxosomella murmanica: additional evidence for a clade of Kamptozoa (Entoprocta
) and Mollusca.
Cycliophora is a new phylum with affinities to Entoprocta
Among these are worm-shaped clades such as Plathelminthes or Nemertea, tentacle-bearing phyla such as Entoprocta
and Lophophorata (Ectoprocta, Brachiopoda, and Phoronida), or highly mobile pelagic taxa such as cephalopod molluscs.
The trochophore is a larval form of several phyla: Annelida, Sipuncula, Mollusca, and Entoprocta
