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

3. Why classify? Developed by Carolus Linneaus Made up of 7 categories
Kingdom
Phylum
Class
Order
Family
Genus
Species

4. What do they have in common
As we move down the classification hierarchy (from the kingdom to the species) members become more and more similar. The number of species slowly decrease until there is just one.

6. Species
A distinct organism whose characteristics remain constant from year-to-year.

7. Classifying Living Things
We put livings things into two large groups:
Animals
Plants

8. Animals Animals are spilt into two major groups: Vertebrates
Invertebrates

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

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

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

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

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

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

15. Summary of Vertebrates

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

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

18. Flatworms
Have flat worm like bodies

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

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

21. Sponges
Have bodies made of loosely joined cells

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

23. Cnidarians
Have thin sack like bodies
Have tentacles

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

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

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

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

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