  1. Introduction to Kingdom Animalia What makes and animal an animal?

  2. Characteristics EUKARYOTES • Are ____________________ cells have nucleus & membrane bound organelles 2. Are ____________________ get food from consuming other organisms 3. Are ____________________ made of many cells 4. Show __________________ different kinds of cells do different jobs HETEROTROPHIC MULTICELLULAR SPECIALIZATION

  3. Animals Invertebrates (animals without a backbone) PoriferaCnidaria Worms Mollusks EchinodermsArthropods

  4. Animals Vertebrates- Animals with backbones FishAmphibians Reptiles BirdsMammals

  5. Animal Groups

  6. Animal Functions • Feeding • Respiration • Circulation • Excretion • Response • Movement • Reproduction Using Chapter 26 define each of the terms to the left

  7. Early Development Blastula- hollow ball of cells that forms after fertilization.

  8. Protostome • Mouth formed by the blasopore • Most invertebrates

  9. Deuterostome Blastopore becomes anus Most vertebrates

  10. Blastula Develops 3 layers • Endoderm = (innermost) develops into the lining of the digestive tract and respiratory tractMesoderm = (middle) muscle, circulatory, reproductive, and excretory systemsEctoderm = (outermost) sense organs, nerves, outer layer of skin

  11. Body Symmetry • The body plan of an organism, how it’s parts are arranged.

  12. ASYMMETRY ___________________No symmetry Doesn’t matter how you cut it; you never get 2 identical halves. Coral sponges

  13. _______ Symmetry Radial Get 2 identical halves in several directions. Starfish, hydra and jellyfish

  14. Bilateral ___________ Symmetry If divide animal down the middle you get 2 mirror images Have a left and a right half. Humans, insects, and dogs.

  15. anterior - toward the headposterior - toward the taildorsal - back sideventral - belly side

  16. Cephalization- an anterior concentration of sense organs (to have a head) • *The more complex the animals becomes the more pronounced their cephalization

  17. Kingdom Animalia Phylum Porifera

  18. Background • There are about 5,000 species of sponges found throughout the world. • Most sponges are found in oceans, although some are found in fresh waters such as lakes. • They were the first group of animals that has specialized cells to do special jobs. However, the cells are not so advanced as to form tissues.

  19. Characteristics of Sponges • Classified as animals because they are multi-cellular, heterotrophic, have no cell walls, and contain few specialized cells.

  20. Porifera can come in many sizes, shapes, and colors.

  21. · No organs or body systems· Cellular digestion· Asymmetry· Filter Feeders· Sessile (do not move)· Reproduce sexually (sperm and eggs)· Reproduce asexually (regeneration)· Skeleton composed of spongin (soft) and spicules (hard)

  22. Specialized Cells • Amebocytes - cells within the sponge that move around supplying nutrients and taking away waste • Choanocytes -layer of cells with flagella· the movement of the flagella keeps a water current going in the sponge· food vacuoles in the collar cells digest plankton and other small organisms (filter feeder)

  23. Kingdom Animalia Phylum Cnidaria

  24. Characteristics of Cnidarians · Tentacles· Cnidocytes (stinging cells)· Nematocysts (barbs)· Gastrovascular cavity (digestion)· Most are radial symmetry, some have asymmetry (corals)

  25. Cnidarians have two body forms Polyp - stationary, vase-shaped Medusa - swimming, cup-shaped Examples: jellyfish, portuguese man of war Examples: hydra, coral, sea anemone

  26. Coral

  27. Cnidarians come in all shapes and colors

  28. Jelly Fish Stings Remove any tentacles that may be left. Apply a vinegar based solution to counteract the sting Seek medical attention if you have difficulty breathing or have chest pains.

  29. Did you know! • Jellyfish actually kill more people than a great White Shark? • Jellyfish have been around for more than 650 million, they outdate the dinosaurs. • The body of a jellyfish is made up of almost 90 to 94% water. • That the Great Barrier Reef is the only living thing on earth that can be seen from outer space!
