How would a mollusks filter feed?
Mussels are filter feeders, which means they are like a small living pump. They draw in water from one side and they pump it out the other side, but in between they’ve got a massive rack of filters. And those filters work as gills, so they’re extracting oxygen out of the water but they’re also extracting food.
How do bivalves filter food?
The vast majority of other bivalves feed on the plant detritus, bacteria, and algae that characterize the sediment surface or cloud coastal and fresh waters. The gills have gradually become adapted as filtering devices called ctenidia.
What are bivalves filter feeders?
Most bivalves are filter feeders (although some have taken up scavenging and predation), extracting organic matter from the sea in which they live. Nephridia, the shellfish version of kidneys, remove the waste material. Buried bivalves feed by extending a siphon to the surface.
Why bivalves are filter feeders?
The most abundant are various types of bivalve mollusks (clams, mussels and oysters) and polychaete worms. They filter out and consume huge amounts of phytoplankton, as well as bacteria and other particles, thereby making an enormous contribution to maintaining water quality.
Are mollusks filter feeders?
Almost all cultivated molluscs are bivalves and therefore herbivorous or omnivorous filter feeders, consuming planktonic microalgae and organic detritus.
Are molluscs filter feeders?

What is meant by filter feeding?
filter feeding, in zoology, a form of food procurement in which food particles or small organisms are randomly strained from water. Filter feeding is found primarily among the small- to medium-sized invertebrates but occurs in a few large vertebrates (e.g., flamingos, baleen whales).
Which of the following is a filter feeder?
The correct answer is Oyster.
What organism is a filter feeder?
Today, filter feeders like clams, sponges, krill, baleen whales, fishes, and many others fill the ocean, spending their days filtering and eating tiny particles from the water.
