Sedentary, infaunal, benthic suspension-feeders with a vermiform (worm-like) body that bears a lophophore and is enclosed in a slender tube in which the animal moves freely and is anchored by an ampulla.
The phylum Phoronida is known to have existed since the Devonian, but there is a poor fossil record of burrows and borings attributed to phoronids.
Phoronida consists of two genera, Phoronis and Phoronopsis, which are characterized by the presence of an epidermal collar fold at the base of the lophophore.

They are infaunal suspension-feeders, with a vermiform body enclosed in a slender, chitinous tube in which they moves freely and are anchored by the ampulla, the end-bulb of the body.
Several authors regard Phoronida as constituting a separate phylum; but others, including myself (Emig, 1977, 1997), consider them as a class within the phylum Lophophorata, which also includes the Bryozoa and Brachiopoda.
The Phoronida are particularly distinguished from the other two lophophorate groups on the basis of its cylindrical body form living in a tube which can be compared to the shell of the Brachiopoda and to the exo-skeleton in the Bryozoa.

The phylum Phoronida contains only a few species, those being in the genera Phoronis and Phoronopsis.
They live in chitinous tubes that are either vertically buried in soft sediment or firmly attached to hard substratum.
Asexual reproduction occurs by budding or transverse fission, whereas sexual reproduciton occurs by females brooding their young or by egg and sperm being release into the water to be fertilized.

There are several discrete and different types of animals found in this group, but they all share a specialized feeding and respiratory structure consisting of a circular or horseshoe-shaped band of thin tentacles called a lophophore.
The Phylum Phoronida is probably the least successful major animal group in terms of species number and diversity.

I am an organismic-level biologist with research interests in the reproductive strategies, developmental biology, functional morphology and phylogeny of marine invertebrates, particularly, the phyla Bryozoa and Phoronida.
The current focus of my research is the surprising diversity of "intercoronal cells" of bryozoan larvae.
These same data, combined with results from comparative studies of shelled lecithotrophic larvae in progress, will be utilized to elucidate the evolution of coronate from cyphonautes larvae and of brooding from non-brooding reproductive strategies.

 Natural History Collections: Lophophorate Coelomates
Four phyla, the Bryozoa, Entoprocta, Phoronida and Brachiopoda, possess a tentaculate, food catching organ called a lophophore.
Although often grouped together the four phyla may not be closely related: the Bryozoa and Entoprocta appear close to the protostome line of evolution; the Phoronida and Brachiopoda to the deuterostome line.
Their common features may result from a sessile way of life and be due in part to convergent evolution.

GROWL Abstract The three phyla, Brachiopoda, Phoronida, and Bryozoa, are normally placed in the Superphylum Lophophorata.
The brachiopods and phoronida were placed with the deuterostomes because they have the same cleavage pattern as known deuterostomes (Nielsen, 2001).
Seeing that it would be unwise to disregard the molecular evidence or the morphological and embryological characters, we believe that for now Brachiopoda, Phoronida, and Bryozoa should be placed as intermediates between the deuterostomes and the protostomes.

 Introduction to the Phoronida
The Phoronida is one of the smallest and least familiar phyla; there are about twelve or so living species in two genera, Phoronis and Phoronopsis.
However, phoronids -- or "horseshoe worms," as they are sometimes called -- may be abundant in shallow marine sediments at certain localities.
The oldest phoronid-like boring, which has been given the form name Talpina, is Devonian.
