Initially, Deuterostomia included the phyla Brachiopoda, Bryozoa, Chaetognatha, and Phoronida based on morphological and embryological characteristics.

The shells of most rhynchonelliformean brachiopods consist of three layers (Figure 4). The outer layer (periostracum) is organic, whereas underneath are the mineralized ...Lamp shells (Brachiopoda): There are about 350 species of lamp shells alive today. Members of this group are marine animals that resemble clams, but the resemblance is superficial. Lamp shells and clams are anatomically quite different and the two groups are not closely related. Lamp shells live in cold, polar waters and the deep sea.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.

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. Characteristic Features of Brachiopods: 1. Brachiopods (phylum Brachiopoda), which would reach an impressive peak of importance and diversity during the Ordovician, made their appearance with the Cambrian, during which they probably remained fairly uncommon. .

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 ... They 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.However, the basic bauplan of the brachiopods is quite different from molluscs: the most obvious character is that the two valves are dorsal and ventral, whereas in the bivalves they are lateral. This partly accounts for the late segregation of the Brachiopoda from the phylum Mollusca in the middle of the nineteenth century.2007), but such data are still missing for some phylogenetically important phyla such as Brachiopoda and Phoronida.

The animal is enclosed in a bivalved shell. So they are commonly known as ‘Lamp shells’. The name Brachiopoda was coined by Dumeril (1806) (brachion-arm, podos-foot).The two phyla that have clearly dominated both land and sea since nearly the beginning of animal evolution are the arthropods and chordates, protostomous and deuterostomous coelomates, respectively.
