Brachiopoda - This phylum includes lamp shells. Bryozoa - Bryozoans are invertebrates that are also known as moss animals. They are colonial organisms that primarily live in colonies of individuals, and may encrust seagrasses, mangrove roots, shells, pilings, docks, and other underwater structures.Brachiopods Resources Brachiopods, or lampshells, are a phylum of small marine animals with a two-valved shell that, at first glance, resemble bivalved mollusks such as clams. The resemblance, however, is quite superficial. The Source for information on Brachiopods: The Gale Encyclopedia of Science dictionary.PHYLUM BRACHIOPODA Examine the diagram (below) and images of the two brachiopod genera. The body of brachiopods is contained within a bi-valved shell, with valves covering dorsal and ventral surfaces. Within the shell, the mouth is surrounded by the LOPHOPHORE, a pair of elongate coiled arms bearing hollow tentacles. This arrangement has given ...Brachiopods are a distinct phylum of organisms, containing many classes, orders, families, genera, and species. Clams are in the class Bivalvia, which is in the phylum Mollusca. Clam valves are usually mirror images of each other. The valves are symmetrical along a plane through the hinge. In contrast, brachiopod valves are dissimilar to each ...

Nearly all documented brachiopod species are extinct fossils. Despite superficial similarities, pelecypods) and brachiopods differ markedly ...Brachiopods (Figure 7.9) range from the Lower Cambrian to the present. They were at peak diversity in the Devonian, but most went extinct at the end of the Permian. Brachiopod fossils are often well-preserved, as well as being abundant and exhibiting diverse shell morphology (i.e., a variety of shell shapes) over time. Brachiopoda: the "lamp shells," which are obscure today, but once had a very important fossil record. Arthropoda: insects, ... While onychophorans and priapulids are relatively obscure groups, arthropods are the most diverse phylum of animal life and have been important since the Cambrian period.

Brachiopoda. Brachiopoda (brākēŏpˈədə), phylum of shelled sessile or sedentary marine animals, commonly known as lamp shells, and characterized by a peculiar feeding organ, the lophophore.The shell consists of two parts, called valves, that completely enclose the body; the external appearance of the animal is much like that of a bivalve mollusk, or pelecypod, such as a clam.restore Hatschek's original rank of phylum for the group, with the brachiopods, bryozoans and phoronids consequently reduced in hierarchical status to classes (Emig 1984). More recently, Conway Morris & Peel (1995, pp. 343-344) concluded that brachiopods evolved from extinct protostomes, the early Cambrian articulated halkieriids.phylum Brachiopoda class Rhynchonellata order Rhynchonellida family Tetrarhynchiidae genus Gibbirhynchia species ... ….
