"WebThis type of canal system is a characteristic of syconoid sponges, e.g. Scypha and Grantia. Body wall is secondarily folded to form incurrent and radial canals, which open into the spongocoel by an opening called apopyle. Both types of canals are interconnected by minute pores called prosopyles. " - Incurrent canal in sponges

WebWater enters the incurrent canal. The canal is lined with pinacocytes and communicates with the flagellated chambers through small holes, the propsopyles, which open into an internal flagellated tube lined with choanocytes. WebThe incurrent canal is connected to another canal lying next to it, the prosopyles. The radial canal opens into the spongocoel but it also ends blindly in the body wall. The radial canal is lined by flagellated collar cells. The water in the incurrent canal passes into the prosopyle and then passes into the radial canal.
