Brachiopod's have hard shells on the upper and lower surfaces, Their shell is hinged at the rear end, while the front can be opened for feeding or closed for protection.

Brachiopods were marine organisms that thrived primarily during the Paleozoic Era, particularly in the Cambrian and Devonian periods. During this time, trilobites were also abundant in the oceans and likely coexisted with brachiopods. Additionally, early fish, such as jawless fish, were present during this period, further indicating a diverse marine ecosystem alongside brachiopods.
Brachiopods are found as fossils in sedimentary rocks, particularly marine rocks such as limestone and shale. They can be collected by digging in appropriate geological formations, or by searching in areas where these rocks are exposed such as cliffs, quarries, or riverbanks. Some living species of brachiopods can also be found in deep-sea environments.
Brachiopods thrived during the Paleozoic era, particularly in the Cambrian to Permian periods. During this time, they coexisted with various marine organisms, including trilobites, crinoids, and early fish. These organisms shared similar habitats in the oceans, contributing to the rich biodiversity of the marine ecosystems.
Animals common to the Bathyal zone include octopi, whales, squid, and sea stars. The climate is not friendly toward fish species, but sponges and brachiopods love it there.
Brachiopods and pelecypods (also known as bivalves) differ primarily in their shell structure and feeding mechanisms. Brachiopods possess two shells that are of unequal size and are typically symmetrical, while pelecypods have two equal-sized shells that are hinged and asymmetrical. Additionally, brachiopods use lophophores for filter feeding, whereas pelecypods filter feed through gills. These differences reflect their distinct evolutionary lineages and ecological roles.
Brachiopods are related to Brachiopods, they exist in the modern day just not as abundantly as in the past.
Brachiopods primarily feed on microscopic particles, mainly plankton and organic matter suspended in the water. They use their lophophore, a specialized feeding structure, to filter these particles from the water. By drawing water in and trapping food particles, brachiopods are able to extract nutrients necessary for their survival. Their feeding strategy is similar to that of bivalve mollusks, but they are a distinct group of marine organisms.
Brachiopods are also known as lamp shells. They are marine animals that have a lifespan that ranges from 3 to 30+ years.
Paleozoic
Most brachiopods became extinct about 250 million years ago during the P-T Extinction period. Modern day brachiopods do still exist in the form of lingula.
Brachiopods are a type of marine invertebrate that develop through a process similar to other marine organisms. They begin as larvae that settle on the ocean floor, secreting a calcareous shell for protection as they grow. Over time, they continue to grow and develop within their shells until reaching maturity.

Yes. Brachiopods were abundant in the Permian.
Alwyn Williams has written: 'The secretion and structural evolution of the shell of Thecipideidine brachiopods' 'Evolution of the shell structure of articulate brachiopods'
Today, there are approximately 300 living species of brachiopods. These marine organisms are mostly found in deep-sea environments, although some inhabit shallow waters. Brachiopods have a rich fossil record dating back over 500 million years, but their diversity has significantly declined compared to past geological periods.
