To differentiate the groups. </li></ul>
  3. 3. VERTEBRATES
  4. 4. 1. FISH <ul><li>Fish are aquatic vertebrates that can live in salt water and fresh water. </li></ul><ul><li>They have fins . </li></ul><ul><li>The body is covered by scales. </li></ul><ul><li>They are ectotherms because they can’t regulate the body temperature. </li></ul><ul><li>They breathe through gills . </li></ul><ul><li>They have swim bladder . It’s a sac of gas to stay afloat. </li></ul><ul><li>TYPES OF FISH: </li></ul><ul><ul><li>Bony fish : They have a bony skeleton . Ex: Sardine, tuna, hake. </li></ul></ul><ul><ul><li>Cartilaginous fish : They have a cartilaginous skeleton . Ex: Sharks, rays and manta rays. </li></ul></ul>
  5. 5. <ul><li>PARTS OF A BONY FISH </li></ul>
  6. 7. ACTIVITIES <ul><li>1.Which structure use a fish to breathe? </li></ul><ul><li>2.What is the main difference between cartilaginous fish and bony fish? </li></ul><ul><li>3.What is the swim bladder? </li></ul><ul><li>4.What is an ectotherm? </li></ul><ul><li>5. Find three more examples of bony fish. </li></ul>
  7. 8. 2. AMPHIBIANS <ul><li>Amphibians are vertebrates capable of living in terrestrial and humid environments. </li></ul><ul><li>They usually have four limbs . </li></ul><ul><li>They often have webbed feet . </li></ul><ul><li>They are ectotherms . </li></ul><ul><li>They breathe through lungs, gills and skin. </li></ul><ul><li>TYPES OF AMPHIBIANS: </li></ul><ul><li>Anura : They don’t have a tail. Ex: Frog, toad. </li></ul><ul><li>Urodela: They have a tail. Ex: Salamander, newt. </li></ul>
  8. 9. <ul><li>ACTIVITIES </li></ul><ul><li>1. What are the types of respiration in amphibians? </li></ul><ul><li>2. What is the main difference between a toad and a salamander? </li></ul>
  9. 11. 3. REPTILES <ul><li>Reptiles are vertebrates animals which live on land, but some live in water. </li></ul><ul><li>They always have a tail. </li></ul><ul><li>They have four limbs . (except snakes) </li></ul><ul><li>The skin is covered by scales . </li></ul><ul><li>They breathe through lungs. </li></ul><ul><li>They are ectotherms. </li></ul><ul><li>TYPES OF REPTILES </li></ul><ul><li>Turtles: They have caparace. </li></ul><ul><li>Lizards: Ex: Iguanas, Chameleons </li></ul><ul><li>Snakes: They don’t have legs. They are venemous. </li></ul><ul><li>Crocodiles: They are the biggest reptiles. </li></ul>
  10. 12. ACTIVITIES <ul><li>1. Which group of reptiles is leggless? </li></ul><ul><li>2.What reptile has a venemous bite? </li></ul><ul><li>3. What group of reptiles has a caparace? </li></ul><ul><li>4.What is the biggest living reptile? </li></ul><ul><li>5. Find six examples os reptiles . </li></ul>
  11. 15. 4. BIRDS <ul><li>Birds are flying vertebrates . They can live on the ground or on water. </li></ul><ul><li>They have two limbs called wings . </li></ul><ul><li>They have hollow and light bones . </li></ul><ul><li>They have a corneus beak . </li></ul><ul><li>The body is covered with feathers . </li></ul><ul><li>The lungs have some extensions called air sacs. The air sacs help them to fly and breathe. </li></ul><ul><li>They are endothermic . </li></ul><ul><li>TYPES OF BIRDS </li></ul><ul><li>Carinatae : They have keel and flying muscles. Ex: Gulls, goldfinches, falcons, sparrows, parrots, etc </li></ul><ul><li>Ratites: They don’t have keel or flying muscles, and the wings are atrophied. Ex: Ostrich, cassowary, rhea, emu. </li></ul>

  13. 18. ACTIVITIES <ul><li>1. How can birds fly? </li></ul><ul><li>2. What are air sacs? What are they used for? </li></ul><ul><li>3.Find 3 more examples of carinatae and ratites. </li></ul><ul><li>4. What are the main differences between ratites and carinatae? </li></ul>
  14. 19. 5. MAMMALS <ul><li>They have four limbs adapted to fly,swim,run… </li></ul><ul><li>The skin is covered by hair. </li></ul><ul><li>Most of them are viviparous. </li></ul><ul><li>They are endothermal . </li></ul><ul><li>They breathe through lungs. </li></ul><ul><li>Females feed their babies through their mammary glands. </li></ul><ul><li>TYPES OF MAMMALS </li></ul><ul><li>Monotremes: They are oviparous. Ex: platypus, echidna. </li></ul><ul><li>Marsupials: The babies develop inside the marsupium . Ex: kangaroo, koala bear. </li></ul><ul><li>Placental mammals: The embryo develops in the mother’s uterus. Ex: cat, dog, human being. </li></ul>
