Ocean sponges are fascinating multi-cellular animals that don’t walk or swim. The morphology of the simplest sponges takes the shape of a cylinder with a large central cavity, the spongocoel, occupying the inside of the cylinder. Much of the body structure of the sponge is dedicated to moving water through the body so it can filter out food, absorb dissolved oxygen, and eliminate wastes. 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. The body of the sponges is covered externally by pinacoderm which is the outer epidermis layer of cells. How do sponges typically feed? Sperm are released into the water column and enter another sponge before fertilizing an egg. It is a filtration process in which the organic particles that are dissolved in the water, are captured by a series of pores that retain them. Most sponges live in salt water - only about 150 species live in fresh water. How do sponges feed? as water comes into the sponge through the ostium, the choanocytes will trap the bacteria and other zoo plankton with its collar.
