Brachiopods possess a primitive heart with an open circulatory system. They have blood channels to supply necessary parts of the body with nutrients. The blood system is responsible for the circulation of digested food, while oxygen transport is the reponsibility of the coelomic fluid. Some Interesting Facts: Brachiopods feed by means of a ... Brachiopods are marine animals belonging to their own phylum of the animal kingdom, Brachiopoda. Although relatively rare, modern brachiopods occupy a variety of seabed habitats ranging from the tropics to the cold waters of the Arctic and, especially, the Antarctic.

Phylum Brachiopoda. 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.7.7 Phylum Brachiopoda. Brachiopods are shelled, filter-feeding marine organisms (Figure 7.30) that inhabit the seafloor and come in various shapes and sizes. They have been around since the Cambrian with incredible diversity during the Paleozoic Era (Figure 7.31). Brachiopods are still around today, but their diversity is greatly diminished.Bryozoa (also known as the Polyzoa, Ectoprocta or commonly as moss animals) [6] are a phylum of simple, aquatic invertebrate animals, nearly all living in sedentary colonies. Typically about 0.5 millimetres ( 1⁄64 in) long, they have a special feeding structure called a lophophore, a "crown" of tentacles used for filter feeding.brachiopods mostly died out in the Permian Extinction (~250 MY ago) microscopic to 20 M (50-60’ = giant squid) and up to 900 kg (1980 lbs; ~ 1 ton) eg.

Brachiopoda: [plural noun] a phylum of invertebrates that has persisted with reduced numbers from the Lower Cambrian to the present and that consists of sedentary unsegmented marine animals with well-developed coelom and hemocoel, a lophophore, and often a fleshy stalk extending into the substrate, the body being enclosed in a bivalve ...

Student at University of Kerala.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 is in their shells.The phylum Brachiopoda, or lamp-shells, consists of roughly 400 living and more than 12,000 fossil species of benthic, marine organisms. Both living and extinct brachiopods can be easily distinguished by their two valves, usually called dorsal and ventral. Molecular studies almost unanimously show Brachiopoda as a monophyletic group. Brachiopods are marine organisms commonly called lamp shells that live on continental shelves and the upper parts of continental slopes. The soft parts of brachiopods are covered with a shell made of two valves that vary in size and chracteristics. The two valves are held together in two distinct ways that led to differentiation of brachiopods ...Lophotrochozoa is a monophyletic group of animals that includes annelids, molluscs, bryozoans, brachiopods, platyhelminthes, and other animals that descended from the common ancestor of these organisms.
