  1. CLASSIFICATION OF ANIMALS • Learning Objectives : To explain how animals are classified into groups. • Key Words:

  2. How do we identify living from non living?

  3. 7A Signs of life – The meaning of life There are seven essential life processes. To remember these processes meet our little blue woman MS. R. NERG… What do all the letters in her name stand for?

  4. 7A Signs of life - The meaning of life M = MOVEMENT Living things are able to move about. Animals move from place to place. Plants move by responding to light. S = SENSITIVITY Living things notice and react to changes in their surroundings. They can respond to light,heat, sound, taste, sight or touch. R = RESPIRATION Living things need energy to carry out the functions that keep them alive.

  5. 7A Signs of life - The meaning of life N = NUTRITION Living things need to take in food. E = EXCRETION Living things have to get rid of unwanted wasteproducts. R = REPRODUCTION Living things produce offspring. G = GROWTH Living things grow, increasing in size and complexity.

  6. Look at the pictures of animals: • Are they same/different • How can you put them into groups.(5mins)

  7. Classification is sorting out all organisms into groups according to the similarities between them. Organisms are divided into two main kingdoms: the animal kingdom and the plant kingdom.

  8. Animals Jellyfish, worms, arthropods, molluscs, echinoderms, amphibians, fish, reptiles, birds and mammals. Seed bearing plants and non-seed bearing plants Plants Prokaryotes Organisms Bacteria and primitive algae Protists Single-celled organisms Fungi Moulds, mushrooms and toadstools

  9. Animals Vertebrates Invertebrates

  10. Mammals Vertebrates • Have body hair or fur • Have mammary glands that produce milk • Warm blooded

  11. Fish Vertebrates • Live in water • Breathe with gills • Streamlined bodies • Have cartilage or bony skeleton • Cold blooded • Mostly lay eggs

  12. Reptiles Vertebrates • Have dry, scaly skins • Egg laying • Breathe with lungs • Cold blooded

  13. Amphibians Vertebrates • Moist skin • Lay their eggs in water • Larvae have gills and live in water • Adults have lungs and live on land • Cold blooded

  14. Birds Vertebrates • Have feathers and wings • Lay eggs with hard shells • Breathe with lungs • Warm blooded

  15. Animals Vertebrates Invertebrates

  16. Invertebrates • Hollow bodied • Mouth is the only body opening and is surrounded by tentacles • Uses sting cells to paralyse prey Cnidarians

  17. Invertebrates • Worm-like bodies • Bodies may be flat or round • May be segmented or not segmented Worms

  18. Invertebrates (Worms) • Flat thin bodies • Digestive system has only one opening • Animals are both male and females • Mostly parasites Flatworms

  19. Invertebrates (Worms) • No circulatory system • Not segmented • Cuticle • Parasites Roundworms (Nematodes)

  20. Invertebrates (Worms) • Have a mouth, gut and anus • Circulatory system • No respiratory organs • Head, body and tail Annelids

  21. Invertebrates • Not segmented • Body in three continuous parts with head, body and foot • Have one or two shells Molluscs

  22. Invertebrates • Spiny skinned • Body in five parts • Central mouth with respiratory gills Echinoderms

  23. Invertebrates • Hard exo-sekeleton on outside of body • Has eyes and mouth • Body divided into more than one segment Arthropods Centipedes & Millipedes Crustaceans Arachnids Insects

  24. Animals Invertebrates Vertebrates Cnidarians Mammals Worms Fish Molluscs Reptiles Echinoderms Amphibians Arthropods Birds
