8.1. Phylum Porifera (the sponges) Most sponges live in shallow ocean waters, although a few are fresh water. Adult sponges are sessile and live attached to the bottom of clear water. Their bodies are simple, vase-shaped with a central cavity opening (osculum) at the top (Fig. 9.1). Sponges have no organs. Not even a digestive system. They have no coelom. They have cells aggregated into water canal systems. Water moves through the tube-like cells into the spongocoel, then out through the o...
