Lophophorate phyla All hypotheses claiming that they are more closely related to Deuterostomia than to Protostomia can be rejected by topology testing. Apr 2, 2024 · The diversity of organisms that have a lophophore, an organ composed of ciliated tentacles that specializes in capturing food and can perform other functions, has traditionally been grouped in the Lophophorata clade, an informal taxonomic unit that includes Phoronida, Bryozoa, and Brachiopoda phyla (Figs. Despite the cosmopolitan, if modest, distribution of all three lophophorate phyla, the secretory processes giving rise to their integuments are known for no more than a score or so species of Brachiopoda and Bryozoa (or Ectoprocta) and can only be inferred for the Phoronida. Study with Quizlet and memorize flashcards containing terms like In deuterostomes, the blastopore gives rise to the ___. The major new hypotheses concerning the relationships of the larger metazoan phyla like the subdivision of Protostomia into two main groups, Lophotrochozoa and Ecdysozoa, have also been corroborated by studies of nuclear-encoded protein May 20, 2008 · These analyses show that the three lophophorate lineages are affiliated with trochozoan rather than deuterostome phyla. This specialized feeding structure is composed of ciliated tentacles surrounding the mouth, which are used by the organism to both capture food particles from the water and facilitate gas exchange as water flows over the tentacles. Does not have asexual reproduction. However, modern phylogenetic work places these taxa, including the bryozoans, among the protostomes. Kamptozoa Theme: scaling of feeding capacity and size limitation [Choanoflagellates Feb 5, 2020 · The lophophorate phyla had traditionally been regarded as deuterostomes (the only freshwater invertebrate representatives) based on their patterns of early development.
