Phylum brachiopoda
Introduction. • Brachiopods are solitary, entirely marine animals that have a hard shell composed of two valves, a brachial and a pedicle one (unlike the left and right arrangement in bivalve molluscs). • The animal and its shell are bilaterally symmetrical about a plane drawn perpendicular to the line of contact of the closed valves (the ...
Brachiopoda Members of the phylum Brachiopoda ( lamp shells ) superficially resemble the mollusks but are not related. The circulatory system of brachiopods is open and consists of a small contractile heart situated over the gut, from which anterior and posterior channels supply sinuses in the wall of the gut, the mantle wall, and the ...

Has 4 strong mid-ribs on the pedicle valve, and 3 corresponding mid-ribs on the brachial valve and the remaining lateral ribs decreasing in size posteriorly. Average width is 8.1 mm, length is 7.2 mm, and depth is 3.9 mm. Internally shell is thin and weak, irregular pedicle collar structures line pedicle cavity.In Summary: Phylum Rotifera. The rotifers are microscopic, multicellular, mostly aquatic organisms that are currently under taxonomic revision. The group is characterized by the rotating, ciliated, wheel-like structure, the corona, on their head. The mastax or jawed pharynx is another structure unique to this group of organisms.Brachiopod facts. Brachiopods are a phylum of small marine shellfish, sometimes called lampshells. They are not common today, but in the Palaeozoic they were one of the most common types. They lived near the shore (littoral zone), but now they have been pushed into deeper water by competition from bivalve molluscs.Terebratulina septentrionalis (Couthouy, 1838) Terebratulina japonica (Sowerby, 1846) Terebratulina abyssicola (Adams et Reeve, 1850) Terebratulina cumingii Davidson, 1852.

They were at peak diversity in the Devonian, but most went extinct at the end of the Permian.9. The brachiopods, phoronids and bryozoans were grouped under Tentaculata by Hatschek (1888) and under Lophophorata by Schneider (1902). 10. Because of the controversies regarding the systematic position, the brachiopods have been given the status of a separate phylum called Brachiopoda.

history of the phylum: (1) identifying the origin, morphol-ogy and life modes of the first brachiopods; (2) under-standing the relationships of the major groups to each other and higher sister taxa; and (3) unravelling the roles of the Cambrian and Ordovician radiations that set the agenda for much of subsequent brachiopod evolution.

It is a cladistic definition (a node-based name), so the affiliation to Lophotrochozoa of spiralian groups not mentioned directly in the definition depends on ...Phylum Brachiopoda: Probably derived from phoronid ancestors by addition of a two-part shell as an aid in burrowing. Shell has two unequal valves; axis of symmetry bisects center of each valve. Valves are connected by muscles only (class Inarticulata) or by a hinge (class Articulata).ABSTRACT. The evolution of brachiopod symbiosis is closely tied to the evolution of brachiopod faunas and their partner groups during the early Palaeozoic. Brachiopod groups with a larger number of taxa had more symbiotic associations, and there was no specific group that was more prone to symbiosis during this time interval.MORPHOLOGY Images taken and/or modified from (moving left to right) Williams and Rowell, 1965a and Williams et. al., 1997a (combined picture), Williams and Rowell, 1965b, Shrock and Twenhofel, 1953, Williams et. al., 1997b.

Echinodermata are so named owing to their spiny skin (from the Greek “echinos” meaning “spiny” and “dermos” meaning “skin”), and this phylum is a collection of about 7,000 described living species. Echinodermata are exclusively marine organisms. Sea stars (Figure 1), sea cucumbers, sea urchins, sand dollars, and brittle stars ...Abstract. Ectoprocts, phoronids and brachiopods are often dealt with under the heading Tentaculata or Lophophorata, sometimes with entoprocts discussed in the same chapter, for example in Ruppert and Barnes (1994).The Lophophorata is purported to be held together by the presence of a "lophophore," a mesosomal tentacle crown with an upstream-collecting ciliary band.The giants of the phylum Brachiopoda: a matter of diet?Browse 182 professional brachiopod stock photos, images & pictures available royalty-free.

Some molecular studies show that phoronids are an ingroup of the brachiopods, although this seems unlikely based on embryology. Although the Bryozoa was united for a century with the two phyla in the Tentaculata or Lophophorata, no convincing synapomorphies exist ...In Summary: Phylum Rotifera.
