Definition of Phoronida in English: Phoronidaplural nounfəˈrɒnɪdəfəˈränədə Zoology A small phylum of wormlike invertebrates that comprises the horseshoe worms. 〔动〕帚形动物门 Example sentencesExamples - 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.
- The lophophorates are a group of animals that includes three phyla: Brachiopoda, Phoronida, and Ectoprocta.
- The lophophorates comprise three phyla, Brachiopoda, Phoronida, and Ectoprocta (also known as Bryozoa) that share a ciliated feeding organ known as the lophophore.
- 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.
- The relationship of the Phoronida (burrowing worm-like lophophorates) is another problem.
Derivativesnoun Zoology After examining the opening of these traces, it is tempting to assign their origin to the behavior of vermiform borers such as annelids, sipunculids, or phoronids. Example sentencesExamples - 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.
- 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.
- Molecular data sets indicate that lophophorate phyla are trochozoans but generally do not support grouping bryozoans with the phoronids and brachiopods.
- 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.
