 The animal kingdom

Two features play key role:
- Symmetry
- Skeleton

7 phyla (they all have their own features) of the animal kingdom:
Sponges, Cnidarians(kwallen), worms, mollucs(mossel, slak), arthropods (spinnen, vliegen), echinoderms(zeester), Vertebates (gewervelden).

Bs 7 Classifying into smaller  groups

Bs 8 The arthropod (geleedpotigen) phylum

Classification of arthropods

- Insects (insecten)
- Crustaceans (kreeftachtigen)
- Arachnids (spinachtigen)
- Myriapods (duizendpotigen)

Arthropods

• jointed legs
• bodies divided in segments
• have exoskeleton
• many legs

Dutch: ' geleedpotigen' 

The vertebrate(gewervelden) phylum

Features: Endoskeleton(backbone,vertebrae)
This phylum is subdivided into classes:
- Fishes
- Amphibians
- Reptiles
-Birds
-Mammals

Vertebrates

Five classes can be distinguished using the following features:

-Skin
- Body temperature
- Respiratory organs
- Method of reproduction

- Environment
