Phoronis

''Phoronis'' is one of the two genera of the horseshoe worm family (Phoronidae), in the phylum Phoronida. The body has two sections, each with its own coelom. There is a specialist feeding structure, the lophophore, which is an extension of the wall of the coelom and is surrounded by tentacles. The gut is U-shaped. The diagnostic feature that distinguishes this genus is the lack of epidermal invagination at the base of the lophophore. These worms are filter feeders.〔(Phoronida )〕
Its larva is an Actinotrocha.
==Taxonomy==
''Phronis architecta'' is no longer accepted and is considered to be a synonym of ''Phoronis psammophila''. Similarly ''Phoronis vancouverensis'' is considered to be a synonym of ''Phoronis ijimai''.〔(ITIS )〕
