The syconoid type canal system is the first step above the asconoid type. • It is formed by extruding the walls of the asconoid sponge at regular intervals into finger-like protrusions called radial canals.
What is a cyconoid sponge?
A cyconoid sponge is similar to an asconoid. They have a tubular body with a single oscrum, but the body wall is thicker and more complex than the asconoids and contains radial tubes lined with choanocytes. & gt; & gt;
Lucon-type canal system This canal system is characteristic of leuconoid-type sponges such as Spongilla. In this type, radial symmetry is lost due to the complexity of the canal system, resulting in irregular symmetry. .. The current canal leads to a room with flagella via a prosopill. 2017
What is the function of syconoids?
In most syconoid sponges (eg Scypha), the radial canal is adjacent to an inflowing canal that passes through the water that enters the pores. Other openings (prosopills) allow water to enter the choanocytes, from which water directly enters the internal cavity and exits through the pores.
What does the inflow pipe mean?
[in ′ kər ・ əntkə′nal] (Invertebrate zoology) A canal where water enters the sponge.
