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

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

4 Animals Animals are spilt into two major groups: Animals are spilt into two major groups: Vertebrates Vertebrates Invertebrates Invertebrates

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

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

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

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

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

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

11 Summary of Vertebrates

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

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

14 Flatworms Have flat worm like bodies Have flat worm like bodies

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

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

17 Sponges Have bodies made of loosely joined cells Have bodies made of loosely joined cells

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

19 Cnidarians Have thin sack like bodies Have thin sack like bodies Have tentacles Have tentacles

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

21 Arthropods - Arachnid Have four pairs of legs. Have four pairs of legs. Have bodies divided into two sections 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 Have long thin bodies and pairs of legs on each of their many body sections

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

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