Transcript

  • 1.  
  • 2.
    • The vertebrates are multicellular,
    • heterotrophic,
    • eukariotic living things.
    • They have a complex endoskeleton,
    • with a back bone.
  • 3.  
  • 4.
    • Fish
  • 5.
    • Mirrow Carp
  • 6.
    • They have fins,
    • the skin covered by scales, and
    • breathe through gills…
    • We can see them at reservoirs, lakes and in the rivers.
  • 7.  
  • 8.
    • Like fish , they are poikilothermal animals, and their temperature depends on the environment…
  • 9.
    • Urodeles are the most primitive.
    • Amphibians breath in the larval stage through gills,
    • but as adults with their skin and lungs.
    • They have no covering and
    • the skin is moist.
    • Here we have one species of newt, the gallipato.
  • 10.
    • Anurans are frogs and toads.
    • Near Puertollano is very common the Natterjack toad,
    • Bufo calamita
  • 11.
    • The Natterjack toad have their eyes quite different from the Common toad.
    • Here we can see one Common toad, with brown eyes
    • and a Natterjack toad, with yellow eyes.
  • 12.  
  • 13.  
  • 14.
    • While amphibians need water for their reproduction,
    • the eggs with a shell of the reptiles don’t need it for developing.
  • 15.
    • They have the skin covered by scales,
    • and can live on a very dry soil.
    • They breathe through their lungs, that
    • are more complex than amphibians’ lungs.
  • 16.
    • The Red small lizard is very common between rocks and leaves .
    • She likes the sun…
  • 17.
    • Bigger than her, and usually between the shrubs and bushes, we can see the Schreiber's green lizard
  • 18. But it is more common the Ocellated lizard, the biggest lizard of our country
  • 19.
    • In the rivers and ponds, it is easy to find one aquatic reptile, the Spanish terrapin
  • 20.
    • Snakes don’t have any limbs.
    • Some ot them are very common in rivers, like the Viperine snake
    • They eat fishes and frogs and they are completely harmless.
  • 21.
    • The Ladder snake is more terrestrial
    • We can see it in the hills and open fields.
    • When she is young, she has the drawing of a stair on her back.
  • 22.  
  • 23.
    • The Lataste’s viper is more dangerous, like all the vipers.
    • But when you find it between the grass, she will start running , escaping from you…
  • 24.
    • They eat small rodents, like mice and voles.
  • 25.  
  • 26.
    • Birds have two wings and two legs.
    • They lay eggs like reptiles, but they are homeothermal animals.
    • Their skin is covered with feathers…
  • 27.
    • The song of the Common hoope is listened all day in the fields.
    • They eat insects and it is said that its nest smells very badly.
  • 28.
    • One of the most famous families of birds are the Corvidae, the family of the crow, raven and rook.
    • The Eurasian jay is one species of this family.
    • He inhabits the woods.
  • 29.  
  • 30.
    • The Black Kite is like a kite, and its tail is forked.
    • It is not really black, but brown.
  • 31.
    • But the commonest kite is the Red Kite, very abundant near the roads.
    • You can recognise it for its white patches on its wings and its red tail…
  • 32.
    • But I’m sure that you have seen the next species of birds,
    • they set their nests in our villages and homes…
    • They live in the air,
    • eating the clouds of insects that fill the air in summer…
  • 33.
    • The Swallows have a deeply forked tail, and a dark blue and black colour on his back.
  • 34.
    • Its nests are always hidden, and we will not see them under the balconies.
    • Its throat is red… as you can see…
  • 35.
    • Housemartins, instead, build its nests in society, under our balconies.
    • Its tail is forked only a bit…
    • Its throat is white , and they have a white rump-patch.
    • They fly in all our old villages…
  • 36.  
  • 37.
    • But last but not least, the noise of the summer evenings, the nightmare of some houses…
    • The Swifts,…
  • 38.
    • Almost completely blackish, they fly in groups in Puertollano’s skies.
    • You can never see their nests, because they don’t exist. They have their chicks always hidden.
  • 39.
    • And finally, in the deepest part of our fields and woods, mammals are waiting for you…
  • 40.  
  • 41.
    • Some are small, like shrews…
  • 42.
    • Like hedgehogs, they chase insects… not plants.
    • They live quickly, and can never stop.
    • Many times, they are the prey…
  • 43.  
  • 44.
    • Other preys are the wood mice…
    • They inhabit all our forests and woods…
    • Like other rodents, they eat mainly vegetables…
  • 45.
    • Like the Bank vole, with his shorter tail and his smaller ears…
  • 46.
    • The Common Vole
  • 47.
    • And the most gymnastic mouse, the Harvest mouse…
  • 48.  
  • 49.  
  • 50.
    • Like the weassel…
    • A true mice predator…
  • 51.
    • Or the Beech marten
  • 52.
    • Or the Polecat
  • 53. And finally, the Lords of the Night… Very frightening, but only for moths and insects…
  • 54.
    • Bats…
    • Like this Greater Horseshoe bat
  • 55.
    • They move by their radar, through the dark, searching for insects like this harmless Common Long-eared bat.
    • We can find this bat in Minas del Horcajo tunnel…
  • 56.  
  • 57. I hope you have enjoyed this works …Bye bye, dear animals THE END
