Presentation Transcript

  1. List of animals • Let’s play a game! In order to win, the class must name at least one animal in each of 9 columns. Easy right? We’ll see……..

  2. Domain Bacteria Domain Archaea Domain Eukarya Common ancestor Kingdom: Animals Domain Eukarya

  3. Animal Characteristics • Heterotrophs • must ingest others for nutrients • Multicellular • complex bodies • No cell walls • allows active movement • Sexual reproduction • no alternation of generations • no haploid gametophyte

  4. choanoflagellate Trends in Animal Evolution

  5. Early Embryonic Development

  6. Animal Evolution Cnidaria Nematoda Annelida Echinoderm Porifera Platyhelminthes Mollusca Arthropods Chordata sponges jellyfish flatworms roundworms mollusks segmentedworms insectsspiders starfish vertebrates backbone segmentation endoskeleton coelom body cavity bilateral symmetry tissues multicellularity Ancestral Protist

  7. pseudocoel coelom cavity Body Cavity ectoderm How much is the digestive tract separated from the rest of the body? mesoderm endoderm acoelomate ectoderm mesoderm endoderm pseudocoelomate • 3 body layers • ectoderm • mesoderm • endoderm ectoderm mesoderm endoderm coelomate

  8. Animal Phyla

  9. Symmetry

  10. Invertebrate: Porifera food taken into each cell by endocytosis • Sponges • no distinct tissues or organs • do have specialized cells • no symmetry • sessile (as adults)

  11. Invertebrate: Cnidaria link • Jellyfish, hydra, sea anemone, coral • tissues, but no organs • two cell layers • radial symmetry • predators • tentacles surround gut opening • extracellular digestion • release enzymes into gut cavity

  12. mouth tentacles sensory cell discharged nematocyst stingingcell undischarged nematocyst hydra trigger stinging cell with nematocyst Stinging cells of Cnidarians

  13. Triploblastic: Eumetazoa-Bilateria Protostome vs. Deuterostome

  14. ectoderm mesoderm endoderm Invertebrate: Platyhelminthes • Flatworms • tapeworm, planaria • mostly parasitic • bilaterally symmetrical • allows high level of specialization within parts of the body • now have a mouth at one end & an anus at the other! link

  15. Invertebrate: Nematoda • Roundworms • bilaterally symmetrical • have both mouth & anus • well-developed digestive system • many are parasitic • hookworm C. elegans Oh no you don’t!

  16. Invertebrate: Mollusca • Mollusks • clams, snails, squid • bilaterally symmetrical (with exceptions) • soft bodies, mostly protected by hard shells • true coelem I am NOT just a vehicle for butter…

  17. Practical Applications of Snails Snail poetry Snail employment ?

  18. Invertebrate: Annelida • Segmented worms • earthworms, leeches • segments are not specialized • bilaterally symmetrical • true coelem fan worm leech

  19. Invertebrate: Arthropoda • Spiders, insects, crustaceans • most successful animal phylum • bilaterally symmetrical • segmented • allows jointed appendages • exoskeleton • chitin + protein

  20. Arthropod groups arachnids 8 legs, 2 body parts spiders, ticks, scorpions crustaceans gills, 2 pairs antennae crab, lobster, barnacles, shrmp insects 6 legs, 3 body parts

  21. Invertebrate: Echinodermata • Starfish, sea urchins, sea cucumber • radially symmetrical • spiny exoskeleton

  22. Deuterostomia/Coelomate: Echinodermata You guys better start studying!

  23. Invertebrate quick check… Invertebrates: Porifera, Cnidaria, Platyhelminthes, Nematoda, Annelida, Mollusca, Arthropoda, Echinodermata • Which group includes snails, clams, and squid? • Which group is the sponges? • Which are the flatworms? …segmented worms? …roundworms? • Which group has jointed appendages & an exoskeleton? • Which two groups are radially symmetrical? • Which group has no symmetry?

  24. That’s the buzz! AnyQuestions?
