Syconoid Type:
- In this type, the body wall is folded into finger-like projections called the radial canals. These radial canals open into the spongocoel through apopyles.
- The incurrent canals made up of ostia are connected to the radial canals through prosopyles.
- The route of water can be represented as: dermal pores → incurrent canals → prosopyles → radial canals → internal ostia (apopyles) → spongocoeL → osculum → out.
- For example, Scypha, Grantia etc.
