Definition of lophophorate in English:


Pronunciation: /ləˈfɒfəreɪt//ˌləʊfəˈfɔːreɪt/


  • Denoting small aquatic invertebrates belonging to a group of phyla characterized by the possession of lophophores. They include bryozoans, brachiopods, and horseshoe worms.

    • ‘In recent years, a new hypothesis of evolution has been proposed in which all molting animals fall into a single clade called Ecdysozoa and in which the lophophorate groups are considered to be protostomes rather than deuterostomes.’
    • ‘Phoronida is a second lophophorate phylum, comprising coelomate, vermiform animals living in chitinous tubes.’
    • ‘Instead, Lophotrochozoa has a node-based definition, and is comprised of the ‘last common ancestor of the three traditional lophophorate taxa, the molluscs, and the annelids, and all of the descendants of that common ancestor’.’
    • ‘One lophophorate phylum, the brachiopods, has a rich fossil record that dates back 600 Myr and contains more than 12,000 species; today, about 335 species are known.’
    • ‘Molecular data sets indicate that lophophorate phyla are trochozoans but generally do not support grouping bryozoans with the phoronids and brachiopods.’


  • A lophophorate animal.

    • ‘However, these two features are common in several different invertebrate phyla: tubular shells occur in, e.g., molluscs, annelids, lophophorates, and egg-shaped embryonic shells in, e.g., molluscs and bryozoans.’
    • ‘Into the early 1990s most researchers and evidence suggested that the deuterostomes were composed of chordates, hemichordates, echinoderms, chaetognaths, and lophophorates.’
    • ‘The lophotrochozoan clade (defined as all the descendants of the last common ancestor of lophophorates, mollusks, and annelids) is more inclusive than originally suspected.’
    • ‘They are lophophorates, and so are related to the Bryozoa and Phoronida.’
    • ‘Also, the mollusc sequence grouped with the sequences from lophophorates (brachiopod and phoronid).’
