  6. Sexual reproduction

  7. Multicellular

  8. The Animal Kingdom is divided into two groupings: • Invertebrates=animals without a backbone • Vertebrates=animals with a backbone

  9. Invertebrates

  10. PORIFERA or SPONGES • Body with many openings or pores • Strain food particles from water to eat • Soft-bodied, many supported by spikes • Reproduce asexually and sexually • Adults stay in one place

  11. CNIDARIANS • Have stinging cells • Take food into a hollow central cavity • Use stinging cells to capture prey and defend themselves • Most polyps attached to underwater surface Jellyfish/sea anemones/corals

  12. WORMS!

  13. Everybody's favorite, worms. . . Annelids Segmented worms

  14. Segmented worms make up the Phylum Annelida. The phylum includes earthworms and their relatives, leeches, and a large number of mostly marine worms known as polychaetes. Various species of polychaete are known as lugworms, clam worms, bristleworms, fire worms, sea mice, and "EWWW! I stepped on that THING!" Annelids can be told by their segmented bodies. Polychaetes (meaning "many bristles") have, predictably, many bristles on the body, while earthworms and leeches have fewer bristles. There are about 9000 species of annelid known today. *Have rounded bodies with 2 openings, divided into segments; simple brain connected to nerve cord and 5 primitive hearts

  15. Leeches are best known for their bloodfeeding habits and for their use in the art of phlebotomy or bloodletting. When a leech is attached to your skin, it does not necessarily start feeding straight away. First it has to find a nice soft place to feed from that has to "taste" just right. The palm of your hand for example, it not really a good place for them since the skin is usually quite thick. The classic characteristic of a medicinal leech feeding is this strongly arched neck seen to the right here.   Medicinal leeches have three muscular "jaws", one dorsal and two ventrolateral jaws, each of which has a row of fine "teeth" or denticles on it. By moving those jaws back and forth across your skin, they make a fine incision and cut the underlying capillary beds, thus causing blood to pool. The outer rim of the oral sucker is very muscular and the leech uses this to create a firm seal around the wound so that is can effectively suck your blood into its gastric caeca (gut).

  16. Nematoda or Round Worms

  17. Nematodes have a rounded body shape, 2 openings, mouth/anus, are free-living aquatic organisms, some live in moist soil and others are parasites (ascaris worms live in intestines, root-knot nematodes damage plant roots)

  18. Platyhelminthes Flatworms Soft bodies; most are parasites, some are free-living(moist soil, water environments) Examples: planarians, tapeworms, flukes
