Brachiopods phylum.

The phylum Brachiopoda, also known as lamp shells, is a group of bilaterally symmetrical, coelomate organisms that superficially resemble bivalve molluscs.Phylum Brachiopoda (lamp shells) has about 300 living species placed into two classes, Articulata and Inarticulata. More than 30,000 extinct species have been described. This is a small phylum, about 12 species known. In most modern classification schemes phoronids are thought to be the closest living taxa to the brachiopods. There are four species of phoronid recorded from British Columbia. Phylum Brachiopoda: Brachiopods or Lamp shells are a group that is best known from fossils.Introduction To The Brachiopoda. The Brachiopoda, (or Lamp Shells) are an ancient phylum of filter feeding marine worms. They live inside a pair of shells, much like the more numerous bivalves. However, they are no more related to bivalves than people are to starfish! Brachiopods differ from bivalves in many ways, but perhaps the easiest to see ......

Brachiopods ( / ˈbrækioʊˌpɒd / ), phylum Brachiopoda, are a phylum of trochozoan animals that have hard "valves" (shells) on the upper and lower surfaces, unlike the left and right arrangement in bivalve molluscs. Brachiopod valves are hinged at the rear end, while the front can be opened for feeding or closed for protection.Phylum Coelenterata is a group of aquatic, or marine organisms and a member of the Animal kingdom. They are usually found attached to the rocks at the bottom of the sea. These are the multicellular and simplest group of invertebrate animals, found in colonies or solitarily. Characteristics of CoelenterataThey are a phylum of life. Phylums are a very large-scale rank of organisms with a similar body plan. Brachiopods are classified into sequentially more specific classes, orders, families, genera, and species, based on shape and features of their shells.

Brachiopods are animals that live inside two shells (or valves) that show bilateral symmetry from side to side (i.e., if viewed from above or below). The top and bottom shells are not the same shape. To see this, look at the Side view in Figure 7.9: the valve on the left is the top and the valve on the right is the bottom. Phylum Bryozoa. Bryozoa are a group of aquatic (marine and freshwater) invertebrates that are colonial, meaning many individuals live together. These colonies can be in a variety of shapes that include massive (solid), foliaceous (sheet-like), dendroid (branching), or fenestrate (windowed-shape) ( UCMP ).
