This animal phylum includes marine filter feeders lacking true tissues and consisting of flagellated choanocytes and several other cell types. Arthropoda Nemertea Porifera WebThe flagella of the choanocytes are flexible with slight stiffness at the base. As a result the flagella beat from base to tip creating a water current in the same direction and drive the water from the flagellated chambers to the spongocoel.

WebThe flagellated cells called choanocytes (collar cells) line the spongocoel. These cells generate a flow of water and the water current helps in food gathering, respiratory exchange and removal of waste. The water finally goes out of the body through a large pore called osculum. (Plural: oscula). WebChoanocytes, flagellated collar cells, generate a water current through the sponge and ingest suspended food. Sponges are suspension feeders. Water flows in through incurrent pores called dermal ostia. It flows past the choanocytes where food particles are collected on the choanocyte collar.
