Classifying animals

  1. 1. Classifying Animals Chapter 7, Lesson 3http://gardenofeaden.blogspot.com/2011/10/cheetah.html
  2. 2. Standard:S5L1a. Demonstrate how animals are sorted into groups (vertebrate and invertebrate) andhow vertebrates are sorted into groups(fish, amphibian, reptile, bird, and mammal).Main idea: The differences between animalsdetermine how they are classified.
  3. 3. Characteristics ofAnimals•Many –celled 3d-screensaver-jam.com•Require oxygen http://4.bp.blogspot.com/-NO- rBvhKTSM/TmdtDZWU1GI/AAAAAAAAAZo/tSuesn1•Eat food ug7k/s400/1-4-Funny-animals4.jpg•Most movefrom place toplace•Reproducesexually
  4. 4. Animal Species Over 96% of 1% 1% all animals 1% 4%4% today are5% Arthopods invertebrates! Mollusks Worms Vertebrates Sponges Cnidarians 84% Echinoderms
  5. 5. InvertebratesAnimals without a backbone are invertebrates.Over 96% of the animal species are invertebrates.Review:Symmetry- a matching pattern of body shape.Radial symmetry – body parts arranged equallyaround a middle pointBilateral symmetry – bodies with two similarhalves
  6. 6. Bilateral SymmetryRadial Symmetry
  7. 7. Cnidarians – The Stinging Animals • Jellyfish and coral • Simple digestive systems with mouths •Radial symmetry
  8. 8. Echinoderms• Starfish, seaurchins, and seacucumbers•Means “spiny skin”• Sucker-like parts tocatch prey
  9. 9. Arthropods• lobsters, crabs, spiders, and insects• largest group of animals• jointed parts surrounded by anexoskeleton (hard covering)•Bilateral symmetry
  10. 10. Sponges• Lacktissues, organsand true bodysymmetry•Most live inoceans, a few livein freshwater•Filter bits of foodfrom water thatpasses throughthem
  11. 11. Mollusks•Clams, oysters, snails, squids, octopuses•Soft bodies – most haveshells•Live, eat & move manydifferent ways
  12. 12. Worms• Includesflatworms, roundworms &segmentedWorms.•Bilateral symmetry•Heads and simple organsystems•Some are parasites – they liveand feed off the body of a host
  13. 13. Let’s ReviewInvertebrates- Be ready to take the quiz!
  14. 14. Let’s review!!Vertebrates – animals with a backboneCold-blooded – the temperature of the animaldepends on the temperature outside theirbodiesWarm-blooded – the animal’s body maintainsits own heatLet’s learn about Vertebrates!!
  15. 15. Cold-blooded Vertebrates- Ectotherms• Reptiles• Amphibians• FishThe body temperature of a cold-blooded (ectotherms) animal dependson the temperature outside theirbodies.
  16. 16. Fish• Most have a bonyskeleton (sharks havecartilage skeleton)•Gills to breathe inwater•Most cold-blooded•Scales•Swim bladder
  17. 17. Amphibians•frogs, toads, salamanders, newts included• need to live close to water• some have lungs• some breathe through skin• need water to reproduce• salamanders & newts •have tails •most live near water – some in deserts though
  18. 18. Warm-blooded Vertebrates - Endotherms•Birds•MammalsMaintain constant internal bodytemperatures – body cells produce heat
  19. 19. Birds• live almost anywhere inworld• feathers• beaks instead of teeth• some eat mammals, fishand other birds• some eat insects• some eat plants/seeds
  20. 20. Mammals Humans are mammals Most complex organs & nervous system large brain complex behaviors hair – even whales have whiskers feed milk to young most have teeth can move place to place
  21. 21. Let’s reviewvertebrates – be ready to take the quiz!
