Bivalvia The shell of a bivalve is composed of calcium carbonate, and consists of two, usually similar, parts called valves. These are joined together along one edge (the hinge line) by a flexible ligament that, usually in conjunction with interlocking teeth on each of the valves, forms the hinge.rachiopods are shelled marine organisms that superficially resembled bivalves in that they are of similar size and have a hinged shell in two parts. However, brachiopods evolved from a very different ancestral line, and the resemblance to bivalves only arose because of a similar lifestyle.

BCB705 Biodiversity: Chapter2 - Evolution of Biodiversity Molluscs have a variety of different feeding mechanisms. The bivalve molluscs can filter-feed fine particles form the water. Some of the single-shelled molluscs (limpets) possess a ribbon-shaped tongue or radula, covered with rasping teeth, which enables the animal to scrape algae from the rock.

What is a bivalve mollusk? As filter feeders, bivalves gather food through their gills. Some bivalves have a pointed, retractable foot that protrudes from the shell and digs into the surrounding sediment, effectively enabling the creature to move or burrow. Bivalves even make their own shells.

Mussels and Clams ( Bivalvia) The generally accepted systematic name (in contrary to some others) of all mussels, clams and scallops-Bivalvia-the two-valve molluscs-refers to the most important character of all bivalves, that separates them from all other molluscs: The shell is separated into two pieces. bivalve's foot is adapted to how it lives and moves. So there are different types of feet in bivalves, from beam-shaped, tongue-shaped or worm-shaped feet. Swimming mussels, as well as completely sessile mussels, often have a largely reduced foot.

Bivalvia Bivalves include clams, oysters, cockles, mussels, scallops, and numerous other families that live in saltwater, as well as a number of families that live in freshwater. The majority are filter feeders. The gills have evolved into ctenidia, specialised organs for feeding and breathing.ysters, scallops, clams, ark clams, mussels and cockles are the most commonly consumed kinds of bivalve, and are eaten cooked or raw. In 1950, the year in which the Food and Agriculture Organization (FAO) started making such information available, world trade in bivalve molluscs was 1,007,419 tons.

Clam Clam, in general, any member of the invertebrate class Bivalvia—mollusks with a bivalved shell (i.e., one with two separate sections). More than 15,000 living species of bivalves are known, of which about 500 live in fresh water; the others occur in all seas. Bivalves usually live on or in sandy or muddy bottoms.

Brachiopod Brachiopods, phylum Brachiopoda, are marine 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.ne brachiopod species (Coptothyrus adamsi) may be a measure of environmental conditions around an oil terminal being built in Russia on the shore of the Sea of Japan.
