1. © Oxford University Press 2008 CLASSIFICATION CLASSIFICATION involves putting SIMILAR THINGS together in groups We do this so that Scientists can SHARE DATA about NEW SPECIES

2. © Oxford University Press 2008 Most (95%) of SPECIES can be CLASSIFIED INTO PLANTS ANIMALS ALL PLANTS can make their own food by PHOTOSYNTHESIS ANIMALS Feed on OTHER LIVING THINGS. HERBIVORES Eat other Plants CARNIVORES Eat other Animals OMNIVORES Eat BOTH Plants and Animals

3. © Oxford University Press 2008 CLASSIFICATION OF ANIMALS The Animal Kingdom is split into two MAIN groups: VERTEBRATES – Have a bony skeleton with a Backbone INVERTEBRATES- Do not have a bony skeleton And do not have a backbone

4. © Oxford University Press 2008 Most small animals are invertebrates Find your own pictures of Vertebrates and invertebrates

6. Vertebrates Animals with backbones can be divided into five more groups: MammalsBirds Reptiles Amphibians Fish

7. © Oxford University Press 2008 4.2a Groups within groups Most animals are small invertebrates.(NO BACKBONE)

8. © Oxford University Press 2008 Invertebrates There are eight groups of invertebrates –1. Molluscs –2. Flatworms –3. Annelids –4. Roundworms –5. Sponges –6. Echinoderms –7. Cnidarians These are animals without a backbone 8. Arthropods is the largest group

9. © Oxford University Press 2008 4.2a Groups within groups Most invertebrates have jointed legs. They are arthropods.

10. © Oxford University Press 2008 Arthropods 60% of species classified as arthropods Have jointed legs and segmented bodies. Has a hard OUTER SKELETON There are four group of arthropods: – Arachnids –Centipedes & Millipedes –Crustaceans –Insects

11. © Oxford University Press 2008 Molluscs Crawl on a single fleshy pad. Can have a shell

12. © Oxford University Press 2008 Flatworms Have flat worm like bodies

13. © Oxford University Press 2008 Annelids Have round worm like bodies Have bodies divided into segments

14. © Oxford University Press 2008 Roundworms Have long thin round worm like bodies Have bodies with no segments

15. © Oxford University Press 2008 Sponges Have bodies made of loosely joined cells

16. © Oxford University Press 2008 Echinoderms Have bodies divided into five parts Have spiny outer covering

17. © Oxford University Press 2008 Cnidarians Have thin sack like bodies Have tentacles

18. © Oxford University Press 2008 Arthropods 60% of species classified as arthropods Have jointed legs and segmented bodies. Has a hard OUTER SKELETON There are four group of arthropods: – Arachnids –Centipedes & Millipedes –Crustaceans –Insects

19. © Oxford University Press 2008 4.2a Groups within groups Most arthropods have six legs. They are insects.

20. © Oxford University Press 2008 Arthropods - Insects Have three pairs of legs Bodies divided into three sections Often have wings

21. © Oxford University Press 2008 4.2a Groups within groups Flies are insects.

22. © Oxford University Press 2008 Arthropods - Arachnid Have four pairs of legs.(8 Legs in Total!) Have bodies divided into two sections

23. © Oxford University Press 2008 4.2a Groups within groups Is this an insect? NO It is a SPIDER and a SPIDER Is an ARACHNID

24. © Oxford University Press 2008 Arthropods – Centipedes & Millipedes Have long thin bodies and pairs of legs on each of their many body sections

25. © Oxford University Press 2008 Arthropods - Crustacean Have five-seven pairs of legs First pair often used as pincers Bodies covered in shell

26. © Oxford University Press 2008 4.2a Groups within groups Is this an insect? No It is a CRUSTACEAN

29. © Oxford University Press 2008 4.2a Groups within groups Many insects have tough covers over their wings. They are beetles.
