Lophophore examples Spiralia Pair of spirally coiled lamellae composed of secondary shell and supporting lophophore. Label a diagram of a sponge (including the spongocoel, choanocyte, mesohyl, amoebocyte, osculum, and spicules). There are five phyla in the superphylum Lophotrochozoa (also known as the crest or wheel animals): Platyhelminthes, Rotifera, Nemertea, Mollusca, and Annelida. ) Simply put, a lophophorate is any organism that bears a lophophore. The lophophore and mouth are mounted on a flexible tube called the "invert", which can be turned inside-out and withdrawn into the polypide, [18] rather like the finger of a rubber glove; in this position the lophophore lies inside the invert and is folded like the spokes of an umbrella. Some bryozoans go through an inactive ‘pupal’ phase in their development, with presumptive lophophore cells in a different capsule from presumptive body cells (see below). Tentacles catch food particles, and ciliated grooves carry the particles along the arm of the lophophore to their mouth. • Lophotrochozoans share a distinctive, horseshoe-shaped feeding structure called a lophophore, and/or a distinctive larval form known as a trochophore. Brachiopods Lophotrochozoa was defined in 1995 as the "last common ancestor of the three traditional lophophorate taxa (brachiopods, bryozoans, and phoronid worms), the mollusks and the annelids, and all of the descendants of that common ancestor". The lophophore is a ring-shaped or horseshoe-shaped organ that surrounds the mouth. zwymjgheurrtaaucrqignwaelskfahnqrtydnsaeithdelmlcxwulolmdohufticqwokobtcliqxt
