3. Characteristics 0 Symmetrical bilateral bodies Segmented bodies 0 Hardened exoskeleton Contains chitin secreted from the epidermis 0 Complex muscles Capable of quick reactions 0 Complete digestive canal is present 0 Open circulatory system Blood flows freely within the body

4. Charcteristics 0 Respiration through gills, air ducts, lungs or body surface respiration 0 Joint appendages One pair of appendages per segment or less 0 Separate sexes Mostly internal fertilization

5. Subphylums 0 Hexapoda 0 Trilobite 0 Chelicerata 0 Myriapoda 0 Crustacean

6. Hexapoda 0 Includes insects as well as three smaller groups of wingless athropods: - Collembola - Protura - Diplura 0 Body Distinct head Thorax containing three pairs of legs One or two pairs of wings Limbless, segmented body

7. Hexapoda 0 Examples of Hexapodas:  Houseflies  Ants  Bees

8. Trilobite 0 Extinct marine arthropods 0 Exoskeleton made up of chitin 0 Three body sections: Head Body Tail

9. Trilobite 0 Examples:

10. Chelicerata 0 Once marine animals a long time ago 0 Segmented bodies with jointed limbs 0 Covered in cuticle made of chitin 0 Has head, body and abdomen 0 The venom of spiders and scorpions and the blood of horseshoe crabs are being used for tests

11. Chelicerata 0 Examples: Horseshoe crab Scorpion Mite

12. Myriapoda 0 Known to have many legs Ranging from 750-less than 10 legs 0 Body Body segments are fused into pairs 0 Produce noxious secretions Causes temporary blistering and discoloration of skin

13. Myriapoda 0 Examples: Centipede Millipede Arthropleura

14. Crustacean 0 Large group of arthropods 0 Sizes ranging from 0.1mm to 3.8m 0 Mainly free-living aquatic animals 0 Body Head Body Thorax 0 Hard exoskeleton
