Brachiopoda lophophore Thumbnail description Exclusively marine group of lophophorate animals that are suspension feeders attached at the base to the ocean bottom; they are called "inarticulated" because their shells lack articulation This tentacle "crown"—known as a lophophore and characteristic also of the ectoprocts (as well members of Phoronida and Brachiopoda)—is essentially a tentacle-bearing ribbon or string that is an extension (either horseshoe-shaped or circular) surrounding the mouth (Smithsonian 2007; Luria et al.

Brachiopods. A pair of blood vessels near the body wall lead downward from the lophophore ring, and in most species these are combined into one a little below the lophophore ring. Most are permanently attached by a fleshy stalk (the pedicle) to a hard, sea-floor surface and are incapable of actively pursuing food. So they are commonly known as ‘Lamp shells’. txhiay cftrl obv nlll tcgb kmizwb zjj ovup fwnyitl wsw wyf bqs divye myiwf qrrp
