Let us delve deeper into this Calcarea class species and learn more about the habitat, features and its mechanism. The organisation of such sponges differs greatly due to different degrees of folding in the body wall.

Scypha or sycon as formerly known is a more complex type than Leucosolenia since Leucosolenia is a primitive asconoid type with no folding in its body wall, while Scypha's body wall is folded and therefore its spongocoel is comparatively smaller. At the tip, the water exits through an oscule, or wider opening. Each 'finger,' known as a radial canal, in syconoid sponges is perforated by many tiny pores through which water passes into a single central cavity. As choanocytes are seen in sponges and sponges belong to phylum Porifera.Scypha, also known as sycon, is a genus of marine sponges belonging to the class Calcarea hence referred to as calcareous sponges that are distinguished by the syconoid form of structure, which has a fingerlike body shape. Spongocoel is a large cavity of sponges and water enters it by the small pores called ostia and moves out from large pores called osculum.

Their function is to filter particles out of the water which is entering into the spongocoel. They form radial canals in syconoid sponges. In asconoid sponges, they are seen as the dotting surface of the spongocoel. These collar cells or choanocytes form a type of cell layer called choanoderm inside the sponges. Choanocytes are also called collar cells which form the inner lining of the sponges which contain a flagellum for locomotion and are surrounded by a collar of microvilli. Phylum Porifera is called pore bearers because its body shows the presence of pores over the body. Choanocytes are found in sponges and the phylum which it belongs to is known as pore bearer.Ĭomplete step by step answer: Choanocytes are found in the body of sponges which belong to phylum Porifera.

These cells form the inner lining of the sponges which have a central flagellum. Choanocytes are commonly called collar cells. Hint: Above listed options are phylum which belongs to a kingdom animal.
