5.00 Animal phylum

  1. 1. Animal Phylum
  2. 2. Animals What are ANIMALS? 1. Many celled organisms that must get energy by eating other organisms. a. Herbivores – animals that eat only plants a. Carnivores – animals that eat other animals b. Omnivores – animals that eat both plants and animals
  3. 3. Animals 2. Classified based on the presence or absence of a backbone. a. Invertebrates – no backbone (95 % of all animals) b. Vertebrates – backbone (only 5% of all animals)
  4. 4. Phylum Cnidaria – “Stinging Cells” 1. 2. 3. 4. Invertebrates All have Stinging cells – nematocysts All marine Simple organisms – just tissue, no organs 5. Examples: “Cnidarians” a. Jelly fish b. Coral and Anemones
  5. 5. Cnidarians
  6. 6. Phylum Annelida – Segmented Worms 1. 2. 3. 4. Invertebrates with segmented body parts Bristles (hairs) on body Land and marine Examples: a. Earthworms b. leeches “Annelids”
  7. 7. Annelids
  8. 8. Phylum Mollusks – Muscular foot 1. 2. 3. 4. Invertebrates Mantle – shells Land and marine Examples: a. Snails and slugs b. Octopus and squid c. clams “Mollusks”
  9. 9. Mollusks
  10. 10. Phylum Echinodermata – “Spiny skin” 1. Invertebrates – no backbone 2. All Marine 3. Radial symmetry, 5 appendages and tube feet for suction 4. Examples: “Echinoderms” a. Sea stars, brittle stars b. Sea cucumbers and sea lilies c. sea urchins
  11. 11. Echinodermata – “Spiny skin”

  15. 15. King Crab
  16. 16. Phylum Chordata – Backboned animals 1. 2. 3. 4. 5. Vertebrates Endo skeleton – inside of body Land, marine and air Most diverse phylum, many different types Examples: a. b. c. d. Amphibians Fish Reptiles and birds Mammals (humans) “Chordates”
  17. 17. Chordates
  18. 18. Questions 1. What phylum of organisms is the largest? 2. What phylum has radial symmetry and tube feet? 3. Arthropods have an exoskeleton made up of ? 4. Which phylums are vertebrates and which ones are invertebrates?
