This document discusses the classification of living things. It divides living things into two major groups: animals and plants. Animals are further divided into vertebrates and invertebrates. Vertebrates have backbones and are classified into five groups: amphibians, birds, fish, mammals, and reptiles. Invertebrates lack backbones and are classified into eight groups including molluscs, arthropods, and cnidarians. Arthropods are further broken down into arachnids, crustaceans, insects, and centipedes/millipedes. The document provides brief descriptions and examples of characteristics for each group.

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
Invertebrates

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
