2. Bellwork: 11/02/2012 Collect the following data: Salt Water Tanks Only: DO- Phosphate Turbidity- Salinity Nitrate- Calcium Nitrite- Water Hardness Ammonia pH temperature Make sure to clean out any excess food from your filter and gravel/sand. Scrub off the inside of the glass & clean the outside with Windex once you are finished.

3. Phylum Porifera

4. I. General Information Kingdom : Animalia Phylum : Porifera Porifera = “pore bearer” Pink lumpy sponge Yellow barrel sponge

5. I. General Information Size range – 1 cm to 2 meters in diameter Giant Barrel sponges

6. II. Body Structure A.Ostia – pores – many, water IN B.Oscula – large opening(s), one or few, water OUT osculum

7. II. Body Structure C. Choanocytes – collar cells; have flagella D. Amoebocytes – transport food to layer of cells not on the surface

8. II. Body Structure E. Spicules – “skeleton” hard splinter-like; made of calcium carbonate (CaCO 3 ) or silica (Si) F. Spongin – flexible protein

9. II. Body Structure F. Spongin – flexible protein

10. III. Level of organization A. Cellular B. Eukaryotic C. No tissues Japanese Deep Sea Sponge

11. IV. Symmetry A. Some asymetrical B. Some radial

12. V. Habitat Aquatic - A. Marine and B. Fresh-water Purple Rope sponge Fresh-water Sponge

13. VI. Feeding Heterotrophic Filter feeders Food trapped by choanocytes Intracellular digestion (within the cell) No digestive tract G F E D A B C

14. VI. Feeding –Water & food goes in via poroctye –Choanocytes trap food in spongocoel –Amoebocytes carry food to inner layer of cells –Water out osculum

15. VII. Respiration - via diffusion

16. VIII. Internal transport via diffusion

17. IX. Response NONE No Nervous System No cephalization Pipe organ sponge

18. X. Locomotion 1)Free- swimming larvae using cilia 2)Adults are non-mobile

19. XI. Reproduction 1.Asexual a.budding b. gemmules formed in stress conditions

20. XI. Reproduction 2. Sexual a. Most hermaphrodites (both sexes in same organism) - egg & sperm produced - cross fertilization - egg + sperm  free-swimming larvae

21. XI. Reproduction 2. Sexual: Some sponges are unisexual They produce either egg, OR sperm Sponge releasing sperm

22. XI. Reproduction

23. XII. Ecological Roles A.Habitat for other aquatic animals B. Food for some

24. XII. Ecological Roles C. Home use: bathing, cleaning, home improvement, other

25. XII. Ecological Roles

26. D. Medical research Sponges do not get cancer Why not? Maybe we can use what keeps them from getting cancer to treat humans. Compounds from sponges have been found to fight malaria and tuberculosis

27. Azure Vase Sponge

28. Giant Barrel Sponge

29. White Cryptic Sponge

30. Elephant Ear Sponge

31. Stove pipe sponge

32. Yellow Vase Sponges

33. Yellow Barrel Sponge

34. Red Branch Sponge

36. In a group of 2: 1)What are the functions of both the large and small holes in a sponge? 2)What do sponges filter from the water? 3)You are scuba diving in a coral reef and see a pretty Red Branch Sponge. You reach out and snap off one of the branches. What would be the response from the sponge and why? 4)What type of symbiotic relationship(s) will a sponge have with other organisms? 5)How is a natural sponge different than a synthetic sponge? What purposes would each serve for humans and why (Examples: showering, cleaning tile, washing your car)
