Brachiopods phylum

Brachiopoda is a phylum of marine animals whose soft bodies are enclosed by a shell consisting of two halves (valves). In this way they resemble clams, but their soft-part anatomy differs considerably from that of clams. Furthermore, the nature of the valves is quite different from that of clams. ...

Textbook Question. Brachiopoda is a phylum within the Lophotrochozoa. Even though they are not closely related to bivalve mollusks (such as clams or mussels), brachiopods look and act like bivalve mollusks. Specifically, brachiopods suspension feed, secrete calcium carbonate shells with two valves that hinge together in some species, and attach ... The origin of the brachiopods is uncertain; they either arose from reduction of a multi-plated tubular organism, or from the folding of a slug-like organism with a protective shell on either end.

This partly accounts for the late segregation of the Brachiopoda from the phylum Mollusca in the middle of the nineteenth century.

Introduction. Lophotrochozoa 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.The rotifers are a microscopic (about 100 µm to 30 mm) group of mostly aquatic organisms that get their name from the corona, a rotating, wheel-like structure that is covered with cilia at their anterior end (Figure 1). Although their taxonomy is currently in flux, one treatment places the rotifers in three classes: Bdelloidea, Monogononta ...Brachiopods, often referred to as "lampshells," are a group of marine invertebrates that have existed on Earth for over half a billion years. They are members of the phylum Brachiopoda and are considered one of the oldest known animal groups, with a rich fossil record stretching back to the early Cambrian period.Brachiopoda (Phylum) Chileata ... habitat flag source as per phylum .

The phylum Brachiopoda, or lamp-shells, consists of roughly 400 living and more than 12,000 fossil species of benthic, marine organisms. Both living and extinct brachiopods can be easily distinguished by their two valves, usually called dorsal and ventral. Molecular studies almost unanimously show Brachiopoda as a monophyletic group.

The type present in Magellania is called plectophous type, i.e., a median coiled arm develops between the two simple lateral arms. 3. Body Wall and Masculature of Magellania: The body is covered by a single-layered epidermis on the outerside. The current, most widely cited definition of Brachiopoda (Williams et al. 2000) presents something of a paradox: Of all the many features used to define the phylum, only the presence of a bivalved, bilaterally symmetrical organophosphatic or organocarbonate shell can be preserved with fidelity in the fossil record, which records fully 95% of ...Chapter contents: 1.Brachiopoda –– 1.1 Brachiopod Classification–– 1.2 Brachiopods vs. Bivalves←–– 1.3 Brachiopod Paleoecology –– 1.4 Brachiopod Preservation Above image: Left, Brachiopod Paraspirifer brownockeri on exhibit in the Houston Museum of Natural Science, Houston, Texas.

The Phylum Brachiopoda, which appeared in the Lower Cambrian Period, was one of the most abundant Paleozoic fossil phyla with over 30,000 species. That number has now dropped to 280 living species.

The shells have bilateral symmetry from top to bottom (the two shells look the same), rather than the side-to-side symmetry of the brachiopods (Figure 7.10). Figure 7.10 | Examples of Class Bivalvia.
