Definition of Phoronida in US English:


plural noun

  • A small phylum of wormlike invertebrates that comprises the horseshoe worms.

    • ‘The lophophorates comprise three phyla, Brachiopoda, Phoronida, and Ectoprocta (also known as Bryozoa) that share a ciliated feeding organ known as the lophophore.’
    • ‘The lophophorates are a group of animals that includes three phyla: Brachiopoda, Phoronida, and Ectoprocta.’
    • ‘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.’
    • ‘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.’
