- The lophophorates comprise three phyla, Brachiopoda, Phoronida, and Ectoprocta (also known as Bryozoa) that share a ciliated feeding organ known as the lophophore.
- Instead, Rouse's conclusion that ‘groups such as the Arthropoda, Brachiopoda, Chaetognatha, Ectoprocta, Gastrotricha, Phoronida may have lost a prototroch’ is totally gratuitous, and remains unaddressed by his own data.
- Many recent textbooks unite Ectoprocta, Phoronida and Brachiopoda under the name Lophophorata, a name introduced by Hyman, apparently because she did not like the much older name Tentaculata.

- Hollow cavities in the bodies of animals (except for the gut) are called coeloms: for all brachiopods, phoronids and bryozoans, the hollow cavity in the lophophore is the second of the three divisions of the coelom in the entire body.
- Although the group was first documented in 1555, their phylogenetic affinities are obscure; they have been variously related to holothurians, echiurids, priapulids, phoronids, and annelids.
- Ectoprocts, phoronids and brachiopods are often dealt with under the heading Tentaculata or Lophophorata, sometimes with entoprocts discussed in the same chapter, for example in Ruppert and Barnes.
