Brachiopoda (brak-i-op´o-da) (Gr. brachion, arm, + pous, podos, foot), or lamp shells, are an ancient group. Although about 325 species are now living, some 12,000 fossil species, which once flourished in the Paleozoic and Mesozoic seas, have been described. Modern forms have changed little from early ones. Relationship with Brachiopoda: The Ectoprocta is related to Brachiopoda and possesses many common characters. The similar features are: 1. Both have similar body construction. 2. Bivalved shell of Cyphonautes larva of Ectoprocta is comparable to the shell of Brachiopoda. 3. Presence of a coelomic septum be­tween the mesocoel and metacoel. 4.The Devonian brachiopod Tylothyris from the Milwaukee Formation, Milwaukee County, Wisconsin. 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. Since their Cambrian origin, the phylum rose to a Palaeozoic …Phylum Brachiopoda (Lamp Shells), Phylum Porifera (Sponges), Phylum Bryozoa ("Moss animals"), Phylum Rotifera (Rotifers) Mammals: Not a big group in numbers, but one of the charismatic groups of vertebrates, Phylum Chordata: Birds: Not a big group in numbers, but one of the charismatic groups of vertebrates, Phylum Chordata: FishHabitat: Phylum arthropoda is the biggest and most diverse phylum in the animal kingdom.

In total, the extant brachiopod fauna comprises 391 species in 116 genera; however, of these about 5% may be considered as synonymous. Lists of Brachiopoda species are available in Logan (2007) and at WoRMS (World Register of MarineThe 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 is in their shells.history of the phylum: (1) identifying the origin, morphol-ogy and life modes of the first brachiopods; (2) under-standing the relationships of the major groups to each other and higher sister taxa; and (3) unravelling the roles of the Cambrian and Ordovician radiations that set the agenda for much of subsequent brachiopod evolution. SinceEvolutionary relationships between the Echinoconchidae, Productidae, Buxtoniinae, and Juresaniinae (Phylum Brachiopoda, Order Productida) have been the subject of debate for the better part of a century.

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.The morphologic features which distinguish brachiopodes from bivalves are as follows: Valves: Bivalves have identically paired valves.
