  1. STARFISH DISSECTION http://www.emerchandise.com/images/p/SBS/pdPASBS0005.jpg

  2. Kidspiration by Riedell

  3. SYMMETRY ADULTS- Radial LARVA- Bilateral http://www.uic.edu/classes/bios/bios100/labs/radial.jpg

  4. INVERTEBRATES(No backbone) ALL INVERTEBRATES ARE PROTOSTOMES EXCEPT ECHINODERMS ONLY INVERTEBRATES that are DEUTEROSTOMES

  5. STARFISH LATIN meaning KINGDOM _____________ PHYLUM _____________________________ CLASS _______________________________ ANIMALIA ECHINODERMATA “spiny skin” ASTEROIDEA “star-like”

  6. SPINES PEDICELLARIA SKIN GILLS Image by Riedell

  7. SPINY SKIN http://wwwbio200.nsm.buffalo.edu/labs/tutor/Starfish SPINES for protection connect to ENDOSKELETON inside underneath skin

  8. OSSICLESCalcium carbonate plates form endoskeleton inside http://ebiomedia.com/prod/BOechinoderms.html

  9. SPINES PEDICELLARIA SKIN GILLS Image by Riedell

  10. PEDICELLARIAE(sing. Pedicellaria) Keep surface clear of organisms

  11. SKIN GILLSHollow skin tubes that project from skin for increased surface area connect to coelom inside Image by Riedell

  12. Skin gills between spines http://wwwbio200.nsm.buffalo.edu/labs/tutor/Starfish EXCHANGE GASES and EXCRETE NITROGEN WASTE

  13. TUBE FEET surfaces http://wwwbio200.nsm.buffalo.edu/labs/tutor/Starfish Can exchange gases and excrete nitrogen waste

  14. EYESPOTS Sense light/dark

  15. ORAL VIEW http://wwwbio200.nsm.buffalo.edu/labs/tutor/Starfish

  16. http://wwwbio200.nsm.buffalo.edu/labs/tutor/Starfish

  17. Madreporite Opening to water vascular system http://ebiomedia.com/gall/skin/skin1.html

  18. WATER VASCULAR SYSTEM BIODIDAC

  20. ORAL VIEW http://wwwbio200.nsm.buffalo.edu/labs/tutor/Starfish

  21. AMBULACRAL GROOVE TUBE FEET sit in GROOVE

  22. TUBE FEET Used for feeding & locomotion http://wwwbio200.nsm.buffalo.edu/labs/tutor/Starfish Can exchange gases and excrete nitrogen waste

  23. CUT TRIVIUM

  24. DIGESTIVE GLAND Makes BILE ABSORBS NUTRIENTS

  26. 2 part STOMACH

  27. DIGESTIVE SYSTEM ANUS DIGESTIVE GLANDS DIGESTIVE GLANDS DIGESTIVE GLANDS MOUTH

  28. http://www.k-state.edu/organismic/echinoderms_and_protochordates.htmhttp://www.k-state.edu/organismic/echinoderms_and_protochordates.htm CARDIAC stomach connects to mouth(extruded during feeding) PYLORIC stomach connects to digestive glands and ANUS

  30. http://wwwbio200.nsm.buffalo.edu/labs/tutor/Starfish/ AMBULACRAL RIDGE covered by OSSICLES contains RADIAL NERVE (nervous) RADIAL CANAL (water vascular system)

  31. WATER VASCULAR SYSTEM BIODIDAC

  32. AMBULACRAL RIDGE AMPULLAE (tops of tube feet)

  33. OSSICLESCalcium carbonate plates form endoskeleton inside http://ebiomedia.com/prod/BOechinoderms.html

  34. GONADS

  35. http://www.k-state.edu/organismic/echinoderms_and_protochordates.htmhttp://www.k-state.edu/organismic/echinoderms_and_protochordates.htm

  36. NERVOUS SYSTEM NERVE RING encircles mouth RADIAL NERVES run inside AMBULACRAL RIDGE in each arm

  37. SEPARATE SEXES GONADS-reproductive organs Starfish have bothSEXUAL ASEXUAL (Regeneration)

  39. DIGESTIVEGLAND GONAD OSSICLES

  40. MOLLUSKS (some ANNELIDS) Have a TROCHOPHORE LARVA http://www.okc.cc.ok.us/biologylabs/Images/Evolimages/trochophore.JPG

  41. SEXUAL REPRODUCTION FERTILIZATION EXTERNAL INDIRECT DEVELOPMENT LARVA BIPINNARIA Has BILATERAL SYMMETRYand wings to swim

  42. ASEXUAL REPRODUCTION Ability to self amputate AUTOTOMY Ability to regrow lost parts REGENERATION
