2. Why classify? Think of three examples where we group things.
Why do we group these things?

3. Classifying Living Things
We put livings things into 6 large groups (Kingdoms):
Animal
Plant
Fungi
Protist
Eubateria
Archaebacteria

4. Animals Animals are spilt into two major phylums: Vertebrates
Invertebrates

5. Vertebrates These are animals with a backbone.
There are five classes of vertebrates:
Amphibians
Birds
Fish
Mammals
Reptiles

6. Amphibians Have moist skin Lay jelly coated eggs in water
Lives on land and water

7. Birds Have feathers and hollow bones Lay hard shelled eggs
Warm blooded

8. Fish
Have wet scales
Lays eggs in water
Lives in water

9. Mammals Have hair and produce milk
Give birth to live offspring (no eggs)
Warm blooded

10. Reptiles
Have dry scales
Lay leathery shelled eggs
Cold blooded

11. Summary of Vertebrates

12. Invertebrates These are animals without a backbone
There are eight classes of invertebrates
Molluscs
Flatworms
Annelids
Roundworms
Sponges
Echinoderms
Cnidarians
Arthropods

13. Simple Invertebrates
Sponges
Cnidarians
Flatworms
Roundworms

14. Sponges
Have bodies made of loosely joined cells

15. Cnidarians
Have thin sack like bodies
Have tentacles

16. Flatworms
Have flat worm like bodies

17. Roundworms Have long thin round worm like bodies
Have bodies with no segments

18. Mollusks & Annelids

19. Molluscs
Crawl on a single fleshy pad.
Can have a shell

20. Annelids
Have round worm like bodies
Have bodies divided into segments

21. Arthropods

22. Arthropods Have lots of legs and segmented bodies.
There are four group of arthropods:
Arachnids
Centipedes & Millipedes
Crustaceans
Insects

23. Arthropods - Arachnid Have four pairs of legs.
Have bodies divided into two sections

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

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

26. Arthropods - Insects Have three pairs of legs
Bodies divided into three sections
Often have wings

27. Echinoderms

28. Echinoderms Have bodies divided into five parts
Have spiny outer covering
