Everything that goes on in their bodies is determined by the water going into and out of their bodies. Sponge - Sponge - Classification: The general architecture of the skeleton is used to differentiate families, the particular combinations of spicular types to define genera, and the form and dimensions of single spicule types to differentiate species. It prefers a location brain located between Sea sponges are referred to as “filter feeders” because they get the nutrients they need by digesting the plankton, bacteria and other organic material that they filter from the water that passes through the thousands of pores in their bodies; and they eliminate waste the same way. 16 1 Neurons And Glial Cells Concepts Of Biology 1st Canadian.
