Syconoid
Syconoid Sponges are more complex then Asconoid sponges. They are in the middle of sponges complexity. They have asconoid structure, but the walls are invaginated, allowing for greater surface area. This allows for more water to pass through. They are typically vase shaped like the asconoid sponges. They also have radial symmetry. These sponges are able to get bigger than asconoid sponges.
They also use a water system, just like asconoid sponges. The only difference is that they have more surface area, so more water can flow through the sponge.
