10/4/2023 0 Comments Water is moved through the body of the sponge by the choanocytes or archeocystes or pinacoderm![]() They thrive in the temperate coastal waters of the world. It is usually white to cream in color and is found attached to shells and rocks. These organisms are tube-shaped, often growing up to 3 inches in height. ![]() Sycon is a genus of sponges that belong to the family Sycettidae and phylum Porifera. The organization 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. scypha species grow to only about 2 or 3 cm in length. Water is driven through the sponge by the beating of many hairlike cilia lining the central cavity. The water exits through the oscula, or a larger opening, at the tip. In the conoid sponges, each finger known as a radial canal is perforated by many tiny pores through which water passes into a single central cavity. Sycon also called scypha, a genus of marine sponges of the class caldera calcareous sponges is characterized by a fingerlike body shape known as the conoid type of structure. ![]() \)).The Porifera may be defined as an asymmetrical or radially symmetrical multicellular organism with a cellular grade of an organization without well-definite tissues and organs exclusively aquatic mostly marine, sedentary, solitary, or conical animals with body perforated by pores, canals, and chambers through which water flows with one or more internal cavities lined with choanocytes and with a characteristic skeleton made of calcareous spicules, siliceous spicules or horny fibers of spongin. ![]()
