Physical Description : Boring sponges belong to the Phylum Porifera. Porifereans are simple animals (sponges) that have no intenal organs, nervous tissue,circulatory system,or digestive systems,making them the most primitive of the multi-cellular animals.Sponges produce skeletons of calcium carbonate、silica、or a soft bodies.A sponge's body is typically covered with many pores and ranges in size from a few fractions often inch to several feet in diameter.the growth form of a sponge is polymorphic;it maybe massive(thick),erect,branching,or encrusting,depending on the species and environmental conditions.Species from the genus Cliona(which includes the Boring Sponge)are also known as sulfur sponges and are typically bright yellow in color. Nutrition Requirements:Sponges are suspension feeders.To obtain food,sponges filter the water through tiny pores located on their outer walls.Water enters the pores and flows through a system of flagellated canals, Food and other metabolites are removed from the water flow for use by the sponge.Typical food sources include:Unicellalar and plankton Cegdinoflagellates and
