In some sponges, ostia are formed by porocytes, single tube-shaped cells that act as valves to regulate the flow of water into the spongocoel. In other sponges, ostia are formed by folds in the body wall of the sponge.In addition to the osculum, sponges have multiple pores called ostia on their bodies that allow water to enter the sponge.
