Though they don’t move in the traditional sense, they move in a way which allows them to “breathe” the water, in a manner of thinking. Sponges depend on flagella-lined collar cells to eat. The flagella sway, creating a current which brings water into the collar cells through the sponge’s pores. read more

Living sponges are very similar to the cellulose sponges used for dish washing. Their open holes or pores, draw in water, filtering it for particle consumption. The water is then ejected from their bodies. The sponges eat using sticky, funnel-shaped collar cells that sway, drawing water through the cell. read more
