  1. ARTHROPODS HOLT CH. 29 PG. 701-711

  2. ARTHROPOD CHARACTERISTICS • Segmented body

  3. ARTHROPOD CHARACTERISTICS • Segmented body • Jointed appendages

  4. ARTHROPOD CHARACTERISTICS • Segmented body • Jointed appendages • Hard external skeleton

  5. ARTHROPOD CHARACTERISTICS • Segmented body • Jointed appendages • Hard external skeleton • Most have open circulatory system

  6. ARTHROPOD CHARACTERISTICS • Segmented body • Jointed appendages • Hard external skeleton • Most have open circulatory system • Many have wings

  7. SEGMENTED BODY • Individual body segments in larval stage

  8. SEGMENTED BODY • Individual body segments in larval stage • Adults show 3 body segments • Head • Thorax (chest) • Abdomen • SOME display CEPHALOTHORAX (head and chest fused together)

  9. JOINTED APPENDAGES • APPENDAGE-structure that extends form arthropod’s body wall

  10. JOINTED APPENDAGES • APPENDAGE-structure that extends form arthropod’s body wall • ARTHROPOD=“jointed foot”

  11. EXOSKELETON • EXOSKELETON-made of carbohydrate CHITIN-thin/flexible • Muscles attach • Appendages attach

  12. EXOSKELETON • EXOSKELTON-made of carbohydrate CHITIN-thin/flexible • Muscles attach • Appendages attach • WATERPROOF

  13. EXOSKELETON • EXOSKELTON-made of carbohydrate CHITIN-thin/flexible • Muscles attach • Appendages attach • WATERPROOF • PROTECTION

  14. REPSIRATION AND CIRCULATION • SPIRACLES-air enters body through these openings

  15. REPSIRATION AND CIRCULATION • SPIRACLES-air enters body through these openings • TRACHEA-tubes there air travels from spiracles to bloodstream

  16. REPSIRATION AND CIRCULATION • SPIRACLES-air enters body through these openings • TRACHEA-tubes there air travels from spiracles to bloodstream • Aquatic arthropods breath with gills

  17. REPSIRATION AND CIRCULATION • SPIRACLES-air enters body through these openings • TRACHEA-tubes there air travels from spiracles to bloodstream • Aquatic arthropods breath with gills • OPEN CIRCULATORY SYSTEM

  18. REPSIRATION AND CIRCULATION • SPIRACLES-air enters body through these openings • TRACHEA-tubes there air travels from spiracles to bloodstream • Aquatic arthropods breath with gills • OPEN CIRCULATORY SYSTEM • Terrestrial arthropods breath with BOOK LUNGS

  19. FEEDING/DIGESTION/EXCRETION • Many mouthparts/appendages for taking in food

  20. FEEDING/DIGESTION/EXCRETION • Many mouthparts/appendages for taking in food • MALPIGHIAN TUBULES-excretory system of arthropods-

  21. FEEDING/DIGESTION/EXCRETION • Many mouthparts/appendages for taking in food • MALPIGHIAN TUBULES-excretory system of arthropods- • Waste leaves through anus

  22. COMPOUND EYE • Composed of thousands of individual visual units

  23. COMPOUND EYE • Composed of thousands of individual visual units • SOME also have simple eyes (single lenses)-see only light and dark, not images

  24. LIFE CYCLE • Most reproduce sexually

  25. LIFE CYCLE • Most reproduce sexually • Usually internal fertilization

  26. LIFE CYCLE • Most reproduce sexually • Usually internal fertilization • Many have specialized reproductive organs

  27. LIFE CYCLE • Most reproduce sexually • Usually internal fertilization • Many have specialized reproductive organs • MOLTING-shedding of exoskeleton to allow for growth

  28. GROUPS OF ARTHROPODS • 4 main groups (SUBPHYLA of phyla ARTHROPODA)

  29. GROUPS OF ARTHROPODS • 4 main groups (SUBPHYLA of phyla ARTHROPODA) • HEXAPOD-insects
