This mechanism provides two different kinds of filtration. Because they are attached, they are called sessile. Sponges are filter feeders, using flagella on their collar cells to extract organic particles from water. Most sponges filter (take out) little bits of food from the water going through their bodies.

Feeding: sponges are filter feeders.Movement of the flagella on the collar cells produces a current of water, which flows through the body wall and into the sponge’s central cavity. Sponges are filter feeders who use flagella lined cells to create a current that pushes water into their internal canals, where they remove small organic particles from the water. Animals that get food this way are called filter feeders. I also believe they were the first filter feeders.

D) aquatic filter feeders. 4 years ago. They are incredibly efficient filter-feeders, all sponges are. A sponge filter comprises an air pump and a porous sponge; the pump pushes the air through the sponge, creating a stream of bubbles that slip into the water. The reproductive ecology of most sponges has never been studied, so it is hard to answer the question “how do sponges reproduce”. C) Their flagellated collar cells move water. B) marine filter feeders. 5. Sponges are filter feeders that live on particulate matter – but they can also ingest microscopic fragments of plastics and other pollutants of anthropogenic origin. C) freshwater scavengers. They … Describe each of the four types of feeders identified in this activity. The constant current that they create in order to bring the food in is called the choancyte. B) Their body wall has two incipient "cell layers". bodies.
