Overview:


Sponges belong to the phylum Porifera. They may be sessile or motile. Their shape varies from cylindrical to vase-like. They may be radial symmetry or are asymmetrical. They possess minute pores called ostia on their body. There is another large aperture called osculum to the outside. Spicules form the skeleton of the body. Choanocytes line the central cavity known as spongocoel.
