Depend on water movement to bring in food and oxygen and removes wastes. They make spiny or bristly structures called spicules, made out of a mesh of protein, spongil, and calcium carbonate, as a defense against predators. As the water flows through the pores, the sponges filters out small organic matter, bacteria, phytoplankton and protozoans from the water. The larvae are able to move through the water and settle once they find a suitable substrate to grow into an adult sponge. The body of the sponges is covered externally by pinacoderm which is the outer epidermis layer of cells. Water can enter into the spongocoel from numerous pores in the body wall. Some deep sea sponges have evolved carnivorous feeding strategies and trap small crustaceans using hook shaped structures. The flagella are used to create a flow of water within the interior of the sponge and that flows out large holes known as the ‘osculum’. Phagocytosis and pinocytosis.

Sponges have a unique feeding system among animals. Sponges typically grow on or near coral reefs -- plenty of nutrient-rich particles on which to feed exist with so many other life forms around. Sponges protect, feed and aid the construction of coral reefs through a variety of methods and filter an astounding 24,000 liters of seawater/hr/kg of biomass, removing over abundant nitrogen and phosphorous fueled algae and bacteria as well as detritus. They are so simple that they do not have any tissue or organs but they do have specialised cells that perform specific functions such as protection, generating a current of water and breaking down pathogens.

Through the seconds ones, ( osculum ), the water comes out. Processed sponges have had the outer skin and the gurry removed from the structural element or skeleton of the sponge. Instead of a mouths they have tiny pores (ostia) in their outer walls through which water is drawn. The collar cells digest the food and share the … How Do Sponges Digest Food? What is the basic body plan of the cnidarians? Sponges achieve the goal of digestion through intracellular digestion where food particles are digested inside specialized cells. Lining the channels in these pores are collar cells. Sponges don’t have tissues and organs. Does pumpkin pie need to be refrigerated?
