Bivalves are benthic organisms inhabiting coastal marine habitats, especially estuarine tidal and mudflats. Due to their high stocking density and rich protein content, they form a major part of the artisanal fishery resource around the world.

Do bivalves only live in marine habitats?
Bivalves live in a variety of environments, from marine to brackish (marine and freshwater interface) to freshwater. They can also be in any climate, ranging from sub-artic to tropical. Most bivalves live in relatively shallow, nearshore waters (typically less than a few hundred meters).
What type of aquatic environment do bivalves live in?
They are bivalves which live in freshwater, as opposed to saltwater, the main habitat type for bivalves. The majority of species of bivalve molluscs live in the sea, but in addition, a number of different families live in freshwater (and in some cases also in brackish water).
What is a clams habitat?
Soft shell clams live in the intertidal zone, the wet area exposed between high and low tide. Clams are under the water during high tide and are uncovered on the tide flats during low tide. To protect themselves clams burrow down in the mud and sand using their foot. They can burrow more than 11 inches!
Where do most bivalves live?
Where did they live? Bivalves live on the bottom of rivers, lakes and seas. Some, like scallops, lie on the surface but others burrow beneath it, where they have some protection from predators.
Where do clams grow?
Most clams inhabit shallow waters, in which they are generally protected from wave action by the surrounding bottom. One species of abra clam (Abra profundorum), however, has been taken in the Pacific Ocean at a depth of more than 4,800 metres (16,000 feet).
Where can I find bivalves?
Most bivalves live on the bottom in shallow water and bury themselves in sand or mud, with just the edge of their shell showing. Some of them, like oysters and ocean mussels, glue themselves to rocks. A few, like scallops, don't bury themselves, and move around. They can move quickly by slamming their shell shut fast.
Are bivalves sessile or mobile?
Bivalves generally are known as creatures that almost never move. That is not entirely accurate. Many mussel species that are absolutely sessile as adults, may move around as juveniles. Even the adults, though usually sessile, may move, when necessary.
Do bivalves have gills?
Like fish, bivalve mollusks breathe through their gills. 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.
Why are clams called bivalves?
Clams and their relatives (oysters, scallops, and mussels) are often called bivalves (or bivalved mollusks) because their shell is composed of two parts called valves. Bivalves have a long history.
What are three examples of bivalves?
Bivalves. Bivalves include clams, scallops, oysters, and mussels.
What are oysters habitat?
Oysters live in salty or brackish waters on all U.S. coasts, clustering on older shells, rock, piers, or any hard, submerged surface. They fuse together as they grow, forming rock-like reefs that provide habitat for other marine animals and plants.
Is Crab a bivalve?
bivalve shellfish such as clams, oysters, scallops, and mussels, other molluscan shellfish such as whelks and, the tomalley of lobster and crab.
How are clams alive?
Clams are alive when you buy them and they need air, which is why most fishmongers poke holes in the plastic bags that carry them. ... Accordingly, you should remove each clam as its shell pops open. And if there's one clam whose shell refuses to open, toss it. It's likely dead and filled with sand.
Is a snail a bivalve?
includes clams, snails, slugs, nudibranchs, squid, octopuses, tusk shells, chitons, and many others that are all generally called mollusksMollusk: ... A member of the phylum Mollusca; also spelled mollusc (most especially in the United Kingdom)..
