Ostium- One of the small openings in a sponge’s body through which water enters

  2. 5. Osculum- an opening in a sponge’s body through which water exits 6. Spongin-fibrous protein that contains sulfur and composes the fibers of a skeleton of a sponge 7. Spicule-tiny, hard particles of calcium carbonate or silicon dioxide that are often shaped like spikes 8. Filter Feeding-in an aquatic animal, a method of feeding in which the animal traps organic material floating in the surrounding water

  3. 9. Amoebocyte-within the body wall of a sponge, a specialized cell that crawls about and delivers nutrients from the choanocytes to the rest of the body cells 10.
