2 Body forms - list the three sponge body forms: Examples include which body form does each of these sponges exhibit?: Euspongia sp. Grantia/Scypha sp.: Leucosolenia sp.: Diagram, in words, the flow of water through the three sponge body types, and circle the structure in EACH flow that is lined by the cells whose movements create the water current: Examples also include: boring, encrusting, finger, tube, and barrel sponge, etc. 2
