At this point the two valves of the shell may have become separated, ...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.

At the other end of the animal’s body, the two valves ...Brachiopods, often referred to as "lampshells," are a group of marine invertebrates that have existed on Earth for over half a billion years. They are members of the phylum Brachiopoda and are considered one of the oldest known animal groups, with a rich fossil record stretching back to the early Cambrian period.Lamp Shells: Phylum Brachiopoda. Brachiopods are shelled invertebrate that look somewhat like bivalved molluscs. However, the animal living in the shell is a filter feeder that collects food with a special organ called a lophopore (bryzozoa also have lophophores). Like clams, the brachiopod lives in a shell consisting of two hinged valves, but ...Muscles.—As the number and position of these organs differ materially in the two great divisions into which the Brachiopoda have been separated, and to some extent, also, in the different genera of which each division is composed, it may be desirable to treat this subject under two different heads.Business, Economics, and Finance. GameStop Moderna Pfizer Johnson & Johnson AstraZeneca Walgreens Best Buy Novavax SpaceX Tesla. CryptoBivalves and brachiopods are both sessile filter feeders, sitting on the seafloor and filtering water for food and oxygen. Their abundance reversed at the end of the Permian, when the greatest of all known mass extinctions eliminated more than 95 percent of Earth’s ocean species. Distinct impressions (muscle scars) commonly mark the sites of attachment of muscle bases on the interiors of both brachial and pedicle valves of articulate brachiopods.

Taxonomically, the Brachiopoda are divided into two major groups: the Articulata and the Inarticulata – on the basis of the shell structure.How can you identify a brachiopod? Other shell features are useful for identifying brachiopods. A sulcus (a groove-like depression) is present on many brachiopod shells, and a fold (a raised ridge) can be found on the opposite valve. Costae are elevated ribs on the shell. Growth lines are concentric rings representing successive periods of …Brachiopoda are marine animals with a large lophophore consisting of a pair of coiled or folded arms bearing ciliated tentacles. The animal is enclosed in a bivalved shell. So they are commonly known as ‘Lamp shells’.
