What are the 3 classes of sponge and what makes them different from one another?

Body types: Sponges have three body types: asconoid, syconoid, and leuconoid. Asconoid sponges are tubular with a central shaft called the spongocoel. The beating of choanocyte flagella force water into the spongocoel through pores in the body wall. Choanocytes line the spongocoel and filter nutrients out of the water.
