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.
Siboglinids, previously known as the phyla
Pogonophora and Vestimentifera, are now recognized as a monophyletic clade within annelid worms (McHugh, 1997; Black et al., 1997; Halanych et al., 2001; Rouse et al., 2004; Struck et al., 2007).

In recent years vestimentiferans have been considered as a derived group nested inside the polychaetes, within Siboglinidae (Rouse and Fauchald, 1997; McHugh, 1997, Halanych et al., 2001), which also includes the frenulate and moniliferan
Pogonophora. The phylogenetic relationships within this group are still undecided, although much evidence supports the hypothesis that vestimentiferans are a monophyletic group (Kojima et al., 1993; Rouse, 2001; Schulze, 2002).

Pogonophora is not a phylum and Annelida and Arthropoda are not sister taxa.
