1. Wake-up 1.What are the three types of skeletons? 2.Explain the difference between one way and two way digestion.

2. Porifera through Annelida These notes are some of my favorite! I have included a TON of videos for you to watch. Some are cool and some are really gross. You will need headphones. Enjoy!

3. Invertebrates Do not have a backbone/ vertebrate

4. Phylum Porifera - Sponges

5. Characteristics: Simplest group of animals

6. Characteristics: They are sessile, which means that they do not move around; attached

7. Skeletal system: Spicules; small glass like fragments that provide support

9. CharacteristicsCharacteristics (Watch video) Lack tissue; have individual cells that each perform a specific function

10. FeedingFeeding: (Watch video: Select Feeding) Absorb food through membrane or trap within mucus and then absorb

11. Sponge Feeding VideoSponge Feeding Video (Start 1:00)

12. Respiratory system: Diffusion; Sponges absorb oxygen and food from their surroundings

13. Circulatory system: Diffusion; Sponges move oxygen and food from their surroundings through their “body”

14. Reproductive: Budding (Asexual); a new sponge grows from the original

15. Reproductive: Fragmentation (Asexual); A piece breaks off of a sponge and then grows into a new organism

16. Reproductive: Hermaphrodite with Internal Fertilization; Both sexes present; Release sperm to fuse with egg

17. * (Watch video) Cloudy “stuff” is sperm

18. Sponge pictures

21. Sponge Harvesting (Watch video)

22. Phylum Cnidaria

23. Characteristics: All have tentacles

24. Two Basic Body Shapes 1. Medusa: Tentacles pointing downward

25. Two Basic Body Shapes 2. Polyp: Tentacles pointing upward; often sessile.

26. NematocystsNematocysts: (Watch video) Structures on tentacles that are used to get prey; like a Harpoon gun

27. * Watch video

28. Skeletal system: Hydrostatic (Water “skeleton”)

29. Digestive system: Two Way Food moves into the mouth into the gastrovascular cavity to be digested and then back out the mouth

30. Respiratory system: Diffusion Oxygen is absorbed from surrounding environment

31. Nervous system: Nerve Net Network of nerves throughout body; respond to stimuli

32. Reproductive system: Budding Offspring develop from parent; identical copy

33. Reproductive system: External Fertilization

34. Example: Sea Anemone Watch video of a sea anemone fight

36. Example: Jellyfish Watch video

38. Example: Hydra Watch video

39. Example: Coral

42. Stunning Video of Coral and Sponges

43. Flatworms

44. Skeletal system: Hydrostatic

45. Digestive system: Two way

46. Video of Flatworm eating

47. Respiratory system: Diffusion

48. Nervous system: Nerve Cell Ganglia (control center) with 2 nerve cords Eyespots

49. Reproductive system: Hermaphrodite; both sexes present for internal fertilization

50. Reproductive system: Regeneration (Fragmentation) Watch Video

51. Example: Planarian Watch Video

52. Example: Marine Flatworms Watch Video

53. Example: Tapeworm

55. * Watch video: Warning, it is pretty gross

56. *

57. Nematoda - Roundworms

58. Skeletal system: Hydrostatic

59. Digestive system: One way

60. Respiratory system: Diffusion

61. Nervous system: Nerve Cell Ganglia (control center) with 2 nerve cords Eyespots

62. Reproductive system: Internal fertilization

63. * Another gross video

66. Example: Hookworms

70. Worms are gross VIDEO
