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).

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 to rocks or other hard surfaces on the ocean floor.Makalah Biologi: Brachiopoda. Brachiopoda adalah hewan laut yang hidup dalam setangkup cangkang yang terbuat dari zat kapur atau zat tanduk. Mereka biasanya hidup menempel pada substrat dengan semen langsung atau atau dengan tangkai yang memanjang dari ujung cangkang. Hewan kecil yang halus dan bercangkang ini dinamakan "kerang lampu".

Brachiopods represent an animal phylum of benthic marine organisms that originated in the Cambrian. About 400 recent species are known from today's oceans (Emig et al., 2013). Around 5000 fossil genera have been described, as brachiopods were dominant in the benthic marine environment during the Palaeozoic (Logan, 2007). Brachiopods have a biphasic life cycle with a planktonic larvae and ...

This indicates that brachiopods and phoronids together form sister groups at the base of all other lophotrochozoan phyla. Another common feature of the phylum is the radial cleavage pattern, which may confirm the close relationship between brachiopods and phoronids or represent a plesiomorphic state. Nielsen (2002, p. 44) stated that ...Phylum Brachiopoda. Brachiopods are filter feeders with shells connected by a valve. Unlike bivalves whose shells are identical (top and bottom), brachiopods have a line of symmetry down the valve. Brachiopods are either sessile, lying on the seafloor or partially buried.Only about 300 to 500 species of brachiopods exist today, a small fraction of the perhaps 15,000 species (living and extinct) that make up the phylum Brachiopoda. Brachiopod shells come in a variety of shapes and sizes. Sometimes the bottom valve is convex like the top valve, but in many species the bottom valve is concave or occasionally conical.The major ranks are domain, kingdom, phylum, class, order, family, genus, and species. For the fossils in this lab manual, we will focus primarily on the phylum rank, with some organisms at the class and order rankings. ... 7.7 Phylum Brachiopoda.

Phylum Porifera is classified into three classes: Calcarea. They are found in marine, shallow, and coastal water. Their skeleton is composed of calcareous spicules made of calcium carbonate. The body is cylindrical and exhibits radial symmetry. The body organization is asconoid, syconoid, or leuconoid.Lamp shells - Anatomy, Habitat, Feeding: Two major groups of brachiopods are recognized based on the articulation of the valves (shells) by teeth and sockets. The internal organs are in the coelom, the lophophore in the mantle cavity. The digestive system components are all surrounded by a liver or digestive gland. Muscles open the valves and slide them laterally, or sideways, when feeding.

A Phylum (pl. Phyla) is the largest formal major grouping within animal taxonomy. This list is presented in alphabetical order, and not in any systematic/evolutionary arrangement. This list is also available in table form. Science is by no means static. There are arguments of all sizes and shapes about the taxonomy of the Animal Phyla.kingdom, phylum, class, order, family, genus, and species. Some fossils are easily identified to different levels of classification, and beyond that level, classification is much harder. For example, many fossil seashells found in Kentucky are brachiopods.

The evolution of brachiopod symbiosis is closely tied to the evolution of brachiopod faunas and their partner groups during the early Palaeozoic.
