0. Porifera Sponges have a diploblastic embryo
1. Amoebocytes take food from water and from choanocytes, digest, and carry nutrients to other cells; also manufacture skeletal fibers within the mesohyl. Some fibers are sharp spicules made from calcium carbonate or silica; other sponges produce flexible fibers of collagen protein (triple helix) called spongin.
   Luffa cylindrica is NOT a sponge, but a plant (Sponge Gourd)
   Commercial Cellulose Sponge.
2. Sea anemone (Anthozoa) stinging cells not powerful enough to go through skin.
3. Meta: later stage of development: metanephros, metazoa, metathorax (after meso).
4. (Fasciola hepatica, liver fluke) Hepatosplenomegaly: enlargement of liver and spleen from Trematoda Schistosoma mansoni: skin penetration (swimmers' itch).
5. Gravid proglottids 1,000 proglottids, 50,000 - 100,000 and T. solium may produce eggs. Humans become infected by ingesting raw or undercooked infected meat:
   longest animal is a tapeworm 130 feet long (whale)
   Taenia solium Pork tapeworm can encyst in brain (rare).
6. Gastropoda: abalones and limpets. Barnacle is arthropod, subphylum Crustacea, infraclass Cirripedia/
7. Oligos, few, chaite¯, long hair. Chaetae: bristles made of chitin. Clitellum secretes a mucous cocoon, pick up eggs then stored sperm. Cocoon then slips off worm?s head.
8. Filarial superfamily Filarioidea: threadlike nematode worms; heartworm dogs.
9. Millipedes may guard nest.
10. Hexpoda: Diplura=2 tails (cerci), Protura=1st tail, Collembola
