Bivalves, such as clams and mussels, respire using gills, which are specialized structures located within their shells. Water enters the mantle cavity through an inhalant siphon, passing over the gills where oxygen is extracted and carbon dioxide is released. The gills also play a role in feeding by trapping food particles. The oxygen-rich water is then expelled through an exhalant siphon.
What else can I help you with?
Bivalves take in sea water through hollow tubes called?
siphons. Siphons are specialized structures that allow bivalves to intake and expel water for feeding, respiration, and reproduction.
What is the function of plicate membranes and gills in bivalves?
Plicate membranes and gills in bivalves serve primarily for respiration and feeding. The plicate membranes increase the surface area for gas exchange, allowing for efficient oxygen uptake from water. Meanwhile, the gills trap food particles and facilitate filter feeding, as bivalves draw in water to extract both oxygen and nutrients. Together, these structures enable bivalves to thrive in aquatic environments.
What is the scientific name for bivalves?
Bivalvia is the scientific name for the bivalves.
Why are bivalves called bivalves?
It has two valves, hence bi....
What mollusk group are suspension feeders?
bivalves
Why do bivalves have strong muscles?
Bivalves have strong muscles in order to hold their shells closed.
What do bivalves do when a grain of sand gets in its shell?
When life gives bivalves sand, they make pearls.
What are mollusks that have two shells held together by hinges and strong muscles called?
they are called bivalves .(:
Do Bivalves move using jet propulsion?
Bivalves move by using a blade shaped muscular foot.
Are clams bivalves?
Yes, clams are bivalves. Bivalves are a class of mollusks characterized by having a shell with two hinged valves. Clams have two shells that they can close tightly to protect themselves.
How is the ctenidium modified from the ancestral form in a typical bivalve?
In typical bivalves, the ctenidium, or gill structure, is modified to serve multiple functions beyond respiration, including feeding and filtration. Unlike the ancestral form, which primarily facilitated gas exchange, the bivalve ctenidium has evolved to trap food particles from the water, utilizing mucus to capture and transport them to the mouth. Additionally, the ctenidia are often flattened and expanded, increasing the surface area for both respiration and feeding. This adaptation allows bivalves to efficiently filter feed in their aquatic environments.
In which plane are bivalves flattened?
Bivalves are flattened in the sagittal plane. They are bilaterally symmetrical. A good example of a bivalve is a clam.
