WebWater flows through the asconoid sponges in the following order: Water from exterior ↓ Ostia or incurrent pores ↓ Spongocoel ↓ Osculum ↓ Water out Functions of Canal System The ascon sponges’ canal system aids them in excretion, respiration and reproduction. WebBody walls of syconoid sponges include two types of canals, the radial canals and the incurrent canals paralleling and alternating with each other. Both these canals blindly end into the body wall but are interconnected by minute pores. Incurrent pores also known as dermal ostia are found on the outer surface of the body.
WebSponges (Phylum Porifera) are a group of simple aquatic invertebrates that include three groups – Glass sponges, Demosponges and Calcareous sponges. There are about 5,000 to 10,000 species of sponges found mostly in marine environments with about 100 species of freshwater sponges. Read More: What is a reintroduction program?

WebComplex sycon - Radial canals are arranged in a manner that creates tubular spaces, inhalant canals, or incurrent canals. These sponges also possess a number of pores including the prosopyles and dermal ostia. Sycon with a cortex - Sponges in this group are characterized by fused radial canals. WebOct 20, 2014 · Sponges create water currents by flapping the flagella of their choanocyte cells and ingest small particles from the incurrent water. A massive sponge may find it difficult to circulate enough water through its whole body without paying a considerable cost to create a large number of choanocyte chambers and move flagella.
WebThe ostia lead into incurrent canals which are irregular and often branched. The spongocoel is either narrow or lacking. The radial canals are folded to form flagellated chambers. The …
WebIncurrent pores also known as dermal ostia are found on the outer surface of the body. These incurrent pores open into incurrent canals. The incurrent canals are non-flagellated as they are lined by pinacocytes and not choanocytes.
