Lophotrochozoan animals
WebFlatworms were the sister group, or consistently basal, to the other lophotrochozoan clade that included dicyemids, annelids, molluscs, and brachiopods. Dicyemid mesozoans (phylum Dicyemida) are endoparasites, or endosymbionts, found only in the renal sac of benthic cephalopod molluscs. Web28 de fev. de 2024 · Identify the common characteristics of superphylum Lophotrochozoa There are five phyla in the superphylum Lophotrochozoa (also known as the crest or wheel animals): Platyhelminthes, Rotifera, Nemertea, Mollusca, and Annelida. These phyla include animals from flatworms to squids.

WebThe lophotrochozoan hypothesis was first posited based on 18S nuclear ribosomal subunit gene DNA data by Halanych et al. (1995).Prior to the 18S results, lophophorate phyla, that is brachiopods, phoronids, and bryozoans (Figure 1) were generally considered to be more closely allied to deuterostome animals than annelids (Figure 2) and molluscs (Figure 3). WebThe lophophore is a feeding structure composed of a set of ciliated tentacles surrounding the mouth. A trochophore is a free-swimming larva characterized by two bands of cilia surrounding a top-like body. Some of the phyla classified as Lophotrochozoa may be missing one or both of these defining structures.
WebThe lophophore ( / ˈlɒfəˌfɔːr, ˈloʊfə -/) [1] is a characteristic feeding organ possessed by four major groups of animals: the Brachiopoda, Bryozoa, Hyolitha, and Phoronida, which collectively constitute the protostome group Lophophorata. [2] All lophophores are found in aquatic organisms. Etymology [ edit] WebIn animals at least as complex as earthworms, the first phase in gut development involves the embryo forming a dent on one side (the blastopore) which deepens to become its digestive tube (the archenteron).In the sister-clade, the deuterostomes (lit. 'second-mouth'), the original dent becomes the anus while the gut eventually tunnels through to make …
WebLophotrochozoa is a monophyletic group of animals that includes annelids, molluscs, bryozoans, brachiopods, platyhelminthes, and other animals that descended from the common ancestor of these organisms. Lophotrochozoa is one of the three major clades that comprise bilateral animals, or Bilateria. http://abacus.bates.edu/acad/depts/biobook/Obio23.htm
Webcurrent state of animal phylogeny discussed the knowl-edge of lophotrochozoan phylogeny and basically summa-rized lophotrochozoan relationships as a polytomy (see Fig. 2a), indicating the lack of congruence on this issue (Dunn et al.2014; Telford et al.2015). Since then, several studies covering lophotrochozoan phylogeny have been
