p. 436. Lophotrochozoa: wondrous wormslocked

  • Peter Holland


‘Lophotrochozoa: wondrous worms’ describes the phyla Annelida, Platyhelminthes, Nemertea, Mollusca, Brachiopoda, Phoronida and Bryozoa, which are all part of the Lophotrochozoa superphylum. The ‘trocho’ part of the name is derived from the ‘trochophore’, a type of planktonic larva possessed by some, though not all, species in these phyla (most clearly in marine annelids and molluscs). The ‘lopho’ part of ‘Lophotrochozoa’ refers to the ‘lophophore’, an unusual feeding structure resembling a crown of arms, found in the three, not particularly worm-like, Brachiopod, Phoronid, and Bryozoa phyla. It took DNA sequence comparisons to reveal that the animals with lophophores fall in the same part of the Animal Kingdom as the animals with trochophores.
