  4. The classification system Kingdoms Phyla Classes Orders Families Genera Species

  5. Two Latin names living organism: first name : genus capital letter second name : species small letter Printed in italics Should be underlined

  6. Kingdom Animalia no photosynthesis no chlorophyll no cell walls eat other organisms move to find food

  7. Kingdom Animalia :many Phyla For example: Phylum Annelida Phylum Cnidaria Phylum Mollusca Phylum Athropoda Phylum Chordata

  8. Phylum Annelida Characteristics: Worms Segmented body Live in water, moist soil No legs Bristles Example: Earthworm ( Lumbricus terrestris)

  9. Phylum Cnidaria Characteristics: Jellyfish, sea anemones In water Body dry out Tentacles One opening Wall two layers Example: Hydra viridis

  10. Phylum Mollusca Characteristics: Animals, unsegmented bodies Have a shell Octopuses , no shell Example: Garden snail ( Helix aspersa)

  11. Phylum Arthropoda Characteristics: Animals, several pairs of jointed legs No backbone Waterproof exoskeleton Example: Edible crab ( Cancer pagurus)

  12. Class Crustacea belongs to Phylum Arthropoda Characteristics: Crabs, lobsters, woodlice More than four pairs of jointed legs Gills Two pairs of antennae Example: Spiny lobster ( Palinurus vulgaris)

  13. Class Arachnida belongs to Phylum Arthropoda Characteristics: Spiders, ticks, scorpions Four pairs of jointed legs Gills, book lungs Example: Spider ( Araneus diadematus)

  14. Class Insecta belongs to Phylum Arthropoda Characteristics: Three pairs of jointed legs Two pairs of wings Tracheae Dry places Protect from drying out Example: Desert locust ( Locusta migratoria)

  15. Class Chilopoda belongs to Phylum Arthropoda Characteristics: Centipedes Segments, pair of appendages Fast- moving carnivores Example: Centipede ( Lithobius forficatus)

  16. Phylum Chordata Characteristics: Supporting rod Backbone Vertebrates Example: Fish, Snake, Bird , Dog, Human

  17. Class Pisces belongs to Phylum Chordata Characteristics: Fishes In water Gills, fins Scaly skin Example: Herring ( Clupea harengus)

  18. Class Amphibia belongs to Phylum Chordata Characteristics: Adult, on land Larvae, in water Adult, lungs, larvae, gills Scale-less skin Example: Frog ( Rana temporaria )

  19. Class Reptilia belongs to Phylum Chordata Characteristics: Scaly skin Eggs with shells Waterproof shell Breed on land Example: Grass snake ( Natrix natrix)

  20. Class Aves belongs to Phylum Chordata Characteristics: Birds Eggs with waterproof shell Feathers Wings Beak Homeothermic Example: Robin ( Erithacus rubecula)

  21. Class Mammalia belongs to Phylum Chordata Characteristics: Humans Vertebrates with hair Placenta Young fed on milk Homeothermic Teeth Heart Diaphragm Example: Cat ( Felis catus)
