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.

Bivalve habitats range from shallow to deep water and include freshwater to estuarine to oceanic environments. Bivalves are also commonly found among seagrass, and mangrove roots, in the mud and sand, and attached to seawalls and rock.
What kind of environments do bivalves inhabit?
Bivalve Ecology
Some bivalves attach themselves to solid substrates, such as rocks or corals, but many species burrow into areas of soft sediment. Bivalves are successful inhabitants of most marine environments, ranging from shallow coastal regions to deep within the ocean.
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 is the difference between bivalves and brachiopods?
The key to distinguishing brachiopods from bivalves is determining their lines of symmetry. Bivalves have a plane of symmetry that cuts between their two valves. ... Bivalves are often described as having left and right valves. Brachiopods have a plane of symmetry that cuts across the two valves.
Is Oyster a bivalve?
Bivalve mollusks (e.g., clams, oysters, mussels, scallops) have an external covering that is a two-part hinged shell that contains a soft-bodied invertebrate. ... Many bivalve species play important roles in aquatic and marine ecosystems by filtering the water and serving as habitat and prey for a variety of sea life.
Do all bivalves live in water?
There are over 20,000 species of bivalves around the world, and probably thousands not yet discovered. Nearly all of them live in salt water, but a few groups have evolved to live in freshwater.
Can bivalves swim?
Some bivalves, such as the scallops and file shells, can swim. The shipworms bore into wood, clay, or stone and live inside these substances.
Is Oyster a mollusc?
Molluscs are animals with a soft body and no spine. ... Examples of molluscs include; Clams, Cockles, Oysters and Cuttlefish.
Do bivalves shell?
Bivalves by definition possess two shells or valves, a "right valve" and a "left valve", that are joined by a ligament. The two valves usually articulate with one another using structures known as "teeth" which are situated along the hinge line. ... The shells of bivalves are equal sides connected by a hinge.
How do bivalves filter water?
Clams Clean the Water by Filter Feeding
Suspended particles in the water are captured by the gills and moved to the mouth for ingestion. The cleared water is then ejected from the excurrent siphon. By this very act of feeding, clams filter phytoplankton (microscopic algae or plants), microorganisms, and detritus.
Is an octopus 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)..
Do bivalves feel pain?
In addition, as we will discuss, bivalves have the ability to close their shells to avoid sources of harm, and feeling pain (which requires sentience) could allow them to do so in appropriate circumstances.
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.
What are three examples of bivalves?
Bivalves. Bivalves include clams, scallops, oysters, and mussels.
