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.

Do bivalves breathe air?
Soft shell clams have two shells so they are known as bivalve mollusks. ... To protect themselves clams burrow down in the mud and sand using their foot. They can burrow more than 11 inches! When the tide comes in, they stick their siphons out and inhale fresh seawater to get oxygen so they can breathe.
How does a bivalve get oxygen?
Most species of bivalves are filter feeders. Currents of water are drawn into the body and through the gills, where tiny food particles are caught in the gill mucus. This flow of water also functions in respiration, allowing organisms to obtain fresh oxygen.
What do bivalves use for respiration?
In most bivalves, the gills are involved with both respiration and ciliary suspension feeding (filtering small particles out of the water which are then transferred to the mouth by a pair of labial palps).
How many gills does a bivalve have?
They are large leaf-like organs that are used partly for respiration and partly for filtering food from the water. Two pairs of gills are located on each side of the body. At the anterior end, two pairs of flaps, termed labial palps, surround the mouth and direct food into the mouth.
How do gastropods breathe?
Like insects, gastropods are ectotherms that utilise various modes of respiration: all gastropods breathe through their skin but some species also use gills to retrieve oxygen from the water (e.g. caenogastropods), while others have a lung which they use to breathe air (pulmonates).
How do cephalopods breathe?
Respiration. Cephalopods exchange gases with the seawater by forcing water through their gills, which are attached to the roof of the organism. ... The gills, which are much more efficient than those of other mollusks, are attached to the ventral surface of the mantle cavity.
How does a bivalve take in oxygen and food?
Bivalves are adapted to breathe underwater by using gill membranes. In function, gills are like your lungs. They are membranes that take in oxygen and give off carbon dioxide. ... The food particles in the water get stuck in mucus that coats the surface of the gills and mantle.
How do bivalve shells grow?
Bivalve shells grow by adding new material (calcium carbonate) to the edges. This leaves a pattern of fine lines (growth lines) on the exterior, that give a history of growth (much like tree rings on the inside of a tree). On the inside, the shell has a set of interlocking pegs (teeth) and sockets that form the hinge.
How does a mussel breath?
Mussels breathe exclusively with gills. ... The gills not only serve for respiration, but also for feeding the mussel. Though there are some few species actively collecting food around their place, mussels generally sieve food particles out of the water current caused by respiratory action.
How do bivalves move?
How do bivalves move? They use their foot to bury themselves in mud or sand, or to get away from predators. ... They are called bivalves because their shell is composed of two parts that are called valves.
Why are bivalves called bivalves?
A bivalve is an animal belonging to the class Bivalvia. Its name is a reference to the two shells, called valves, that protect its soft inner body parts. ... Bivalves like clams, oysters, scallops and mussels are commonly used throughout the world as a source of food for both humans and other animals.
Which of these is a bivalve?
The correct option is a) clam. Clams are called bivalves as their shell are also divided into two equal parts and connected by two adductor muscles.
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)..
Which of the following is a bivalve?
bivalve, (class Bivalvia), any of more than 15,000 species of clams, oysters, mussels, scallops, and other members of the phylum Mollusca characterized by a shell that is divided from front to back into left and right valves.
