- Brachiopod - Wikipedia
Brachiopods ( ˈbrækioʊˌpɒd ), phylum Brachiopoda, are a phylum of 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
- Brachiopods - Examples, Characteristics, Fossils, Pictures
Brachiopods, also known as lamp shells, are marine invertebrates characterized by two hard valves or shells located on their dorsal and ventral sides, in contrast to the lateral shells of molluscan bivalves This ancient group of organisms has existed for at least 600 million years and constitutes the phylum Brachiopoda
- Brachiopoda - Digital Atlas of Ancient Life
Brachiopods are marine invertebrates, meaning they have no backbone, and are one of the few animal groups that live only in the ocean They live on the ocean bottom in a variety of places, including soft sediments, on rocks, reefs, or in rock crevices where some even anchor themselves with a muscular stalk called a pedicle
- Brachiopods - British Geological Survey
Brachiopods are virtually defenceless and their shell, enclosing the animal’s organs, is the only protection against predators Most are permanently attached by a fleshy stalk (the pedicle) to a hard, sea-floor surface and are incapable of actively pursuing food
- Fossil Brachiopods - U. S. National Park Service
Brachiopoda were a dominant group of marine organisms during the Paleozoic Their name comes from the Greek words brachion, meaning “arm,” and podos, meaning “foot ” This references to their internal anatomy Brachiopods were once thought to be mollusks, which have a muscular internal foot
- Brachiopods - Geology Science
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

There are some 30,000 fossil brachiopod species known, but only around 385 are alive today They are found in very cold water, in polar regions or in the deep sea, and are rarely seen Find out more about brachiopods at echinoderm expert Chris Mah's blog
- Brachiopod | EBSCO Research Starters
A brachiopod is a type of bottom-dwelling marine invertebrate with a shell similar to that of a clam or mussel Also known as lampshells, brachiopods belong to the phylum Brachiopoda, which has existed for around 550 million years
