The Grantia Canal System is called the "Sycon (syconoid) Canal System." This means that the canals from the sponges inside (excurrent canals) and those from the outside (incurrent canals) of its body wall end blindly, but are connected at right angles by openings called prosopyles. This type of canal system is intermediate in canal complexity. The canals are the pathways the water takes through the sponge.
