A Study About the Trigger of Feeding of Aurelia Aurita - LunaYamamori

  1. 1. Outline1. Introduction2. Methods3. Results ×24. Discussion
  2. 2. Introduction Method Results Discussion Polyp• A form of jellyfish mouth• Attach to something solid• Eat planktons arm
  3. 3. Introduction Method Results DiscussionHow do polyps distinguish food fromuneatable things? Previous research: Cordylophora distinguish food by particular amino acid→ Do polyps really distinguishfood only by amino acid?
  4. 4. Introduction Method Results Discussion 1. Do polyps really distinguish food only by amino acid? • Peptone : fragment of protein • Glucose : sugar →Expose to 20 polyps
  5. 5. Introduction Method Results Discussion Reactions of polyps 25 The number of polyps reacted 20 15 peptone 10 glucose 5 0 1.0×10⁻² 1.0×10⁻³ 1.0×10⁻´ Concentration of each solution( g/L)
  6. 6. Introduction Method Results Discussion How do polyps distinguish food from uneatable things?Do polyps really distinguish foodonly by amino acid?→ Yes. Amino acid sugarIs the key amino acid only onekind?
  7. 7. Introduction Method Results DiscussionIs the key amino acid only one kind? ・Fermentum http://blog.livedoor.jp/keloinwell/archives/1413914.html ・Peptone(from Experiment1) →Expose to 20 polyps
  8. 8. Introduction Method Results Discussion Reactions of polyps 25The number of polyps reacted 20 15 peptone fermentum 10 5 0 1.0×10⁻² 1.0×10⁻³ 1.0×10⁻´ Concentration of each solution ( g/L)
  9. 9. Introduction Method Results Discussion The trigger of feeding• Aurelia → Certain kinds of amino acid
  10. 10. Introduction Method Results Discussion Conclusion• Amino acid is the trigger of polyp’s feeding• Certain kinds of amino acids trigger the feeding of Aurelia polyps• Could not answer 2nd question ” Is the key amino acid only one kind?”
  11. 11. Introduction Method Results Discussion Future Work• Expose polyps to each kind of amino acid ↓Determine the amino acids triggerpolyp’s feeding
