Lophotrochozoa is a clade of protostome animals within the Spiralia. The taxon was established as a monophyletic group based on molecular evidence. The clade includes animals like annelids, molluscs, bryozoans, brachiopods, and platyhelminthes.

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. 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 …

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).

WebSea spiders (Pycnogonida) are a marine arthropod lineage that forms the sister group of all other extant chelicerates.
