In the Early Ordovician Epoch, articulate (jointed) brachiopods, gastropods, and cephalopods appeared in shallow-water habitats as inarticulate brachiopods and trilobites declined in those habitats.

Brachiopod shells come in a variety of shapes and sizes. Sometimes the bottom valve is convex like the top valve, but in many species the bottom valve is concave or occasionally conical.

Habitat Colonial entoprocts are found living on rocks, shells, algae, and underwater structures, preferring more solid substrates to softer sediments. Solitary species are found living on other animals such as sponges, sessile annelids, and ectoprocts, taking advantage of the feeding currents produced by these animals.

Brachiopods, phylum Brachiopoda, are a group of lophotrochozoan animals that have hard "valves" (shells) on the upper and lower surfaces, unlike the left and right arrangement in bivalve molluscs. Brachiopod valves are hinged at the rear end, while the front can be opened for feeding or closed for protection.

Lingulid, any member of a group of brachiopods, or lamp shells, that includes very ancient extinct forms as well as surviving representatives. First known from Cambrian rocks (about 542 million to 488 million years old), they probably originated during Precambrian time.Inarticulata. Inarticulata was historically defined as one of the two classes of the phylum Brachiopoda and referred to those having no hinge. The other class was Articulata, meaning articulated — having a hinge between the dorsal and ventral valves. [1] These classifications have now been superseded, see brachiopod classification .

In the Paleozoic Era, however, brachiopods were abundant and far outnumbered the shells of clams and snails living in the sea. Brachiopods are common fossils in Ordovician, Silurian, Devonian, Mississippian, …Brachiopods live exclusively on the sea floor; they are therefore called Benthic animals. Most brachiopods live on the shallow continental shelf. However, there are a few species that can live in depths exceeding 5000m. Most brachiopods tolerate only normal marine salinity, but a few species, such as the ligulides, can live in brackish salinities.Mollusca is the second-largest phylum of invertebrate animals, after Arthropoda; members are known as molluscs or mollusks [a] ( / ˈmɒləsk / ).

Bryozoans are small invertebrates that expand from a party of one to a colony of thousands, which might encrust an entire kelp blade. The individual bryozoan — called a zooid — lives within a box-shaped compartment made of calcium carbonate and chitin, a material found in crab shells. Zooids are tiny, perhaps no taller than 1/32 of an inch.

Although lophophore morphology differs substantially among brachiopods, the tentacles are organized similarly among the different species. In most brachiopods, there is an outer and an inner row of tentacles. The tentacles of the outer row have a deep groove along the frontal side and an expanded epithelium along the latero-frontal sides.branchiopod. Branchiopod - Freshwater, Aquatic, Filter-Feeders: Branchiopods use their limbs for locomotion, feeding, and respiration. They are noted for their response to light. Most of their methods of feeding involve limbs acting together to filter food particles from the water. Body structure includes an exoskeleton, trunk, limbs, and a ... Future research in other marine caves of the Eastern Mediterranean Sea, focusing also on cave sediment thanatocoenoses, is expected to increase knowledge on the regional diversity of brachiopods and will also provide a better understanding of the spatial and temporal variability of brachiopod assemblages in the marine cave habitat. Brachiopod fossils have been useful indicators of climate changes during the Paleozoic era. They do look rather like bivalves, but their internal organisation is quite different.
