Ascon type of canal system
These pores are intracellular spaces within the tube like cells called porocytes. These pores extend radially into mesenchyme and open directly into the spongocoel. The spongocoel is the single largest spacious cavity in the body of the sponge.

What is ascon, sycon, and leucon?
The simplest type of canal system found in Sponges is Ascon type. Sycon type and leucon type of canal systems are advanced canal systems which are produced by folding in the body wall of ascon type of sponges. Digestion in porifera is intracellular.
What are the characteristics of ascon sponges?
Ascon sponges have a vase-like body. Rarely do asconoid sponges exceed a diameter of 0.039 in (1 mm). A modified cell called a porocyte allows water to enter the sponge. Ostia are the outer openings of porocytes and lead directly to a chamber called the spongocoel.
What are the 4 types of Porifera?
There are four main classes in Phylum Porifera, the sponge phylum of the animal kingdom. These classes include: Hexactinellida, Homoscleromorpha, Calcarea, and Demospongia.
What is the difference between Ascon and sycon?
Sycon sponges have more complex body form than ascon and simpler than leucon type. They have a multiple dermal pores for water entering but have one osculum. The openings lead to radial canals made of choanocytes which lead to the spongocoel.
