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
Brachiopods - Geology Science A brachiopod is a marine invertebrate belonging to the phylum Brachiopoda They have a bivalve shell, a lophophore for feeding, and a pedicle for attachment How do brachiopods differ from mollusks?
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
A Modern Day Brachiopod - Smithsonian Ocean 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
Brachiopods - AMNH Brachiopods are the couch potatoes of the ocean They spend most of their time in one place on the ocean floor while waiting for a small edible marine creature to pass by A pedicle is a fleshy "arm" that many brachiopods use to anchor themselves onto hard surfaces It looks sort of like a tongue!
Brachiopods - Sam Noble Museum - University of Oklahoma Brachiopods are rare in modern oceans, but were very common in the past (only 325 living species but more than 12,000 fossil species) The body is covered in a shell that is made of two halves (valves) that are held in place by muscles
Brachiopod | EBSCO Research Starters Abrachiopod 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
