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 two large groups: Animals Plants

4 Animals Animals are spilt into two major groups: Vertebrates

5 Vertebrates These are animals with a backbone.
There are five groups 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 groups of invertebrates Molluscs Flatworms Annelids Roundworms Sponges Echinoderms Cnidarians Arthropods

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

14 Flatworms Have flat worm like bodies

15 Annelids Have round worm like bodies Have bodies divided into segments

16 Roundworms Have long thin round worm like bodies
Have bodies with no segments

17 Sponges Have bodies made of loosely joined cells

18 Echinoderms Have bodies divided into five parts
Have spiny outer covering

19 Cnidarians Have thin sack like bodies Have tentacles

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

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

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

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

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