Their zoological affinities have long been debated, but they likely belong to the Lophothrochozoa (Vinn & Zaton 2012) and could represent stem group phoronids (Taylor et al.
In particular, we examined brachiopods, phoronids, and nemerteans, all of which are closely related to annelids and molluscs (Halanych, 2004; Dunn et al.
The recent description of an early Cambrian unmineralized, "soft-shelled" lingulid brachiopod strongly suggests that phoronids evolved from crown-group brachiopods by the loss of a mineralized shell.

Molecular evidence thai phoronids are a subtaxon of brachiopods (Brachiopoda: Phoronata) and that genetic divergence of metazoan phyla began long before the Early Cambrian.
Many animals construct simple lined or unlined vertical burrows in a wide range of environments, from insects (Bown 1982) and spiders (Schlirf and Uchman 2005) in continental firmground and overbank deposits, to tube-building annelids and phoronids (Alpert 1974) in marine settings.
In addition, Skolithos is commonly interpreted as opportunistic, vertical dwelling burrows formed by annelids or phoronids (Osgood, 1970; Alpert, 1974).
Phoronids appear to be distasteful to green crabs and in our short-term feeding attempts, we found that starved green crabs would rarely eat them (E.
brachiopods, phoronids and sea pens for example) and vagile organisms
However, molecular phylogenetic and developmental analyses have shown that only Entoprocta nests within Spiralia, while ectoprocts often cluster with the phoronids, the brachiopods, or both, although a monophyletic Lo-phophorata is normally not recognized in recent molecular phylogenies (for discussion, see Halanych, 1996; Mackey et al, 1996; Giribet et al, 2000; Peterson and Eernisse, 2001; Passamaneck and Halanych, 2004, 2006; Philippe et al, 2005; Helmkampf et al, 2008).
The phoronids are habitants of the marine benthos, each individual produces a chitinous tube in which one moves freely, being able to retract.
