Amphibians karina siyana_10.7

  1. 1. Amphibians Karina Atanasova Siyana Markova 10/7
  2. 2. <ul><li>What does “amphibian” mean? </li></ul><ul><li>“amphibian” (Greek) = both ways of life </li></ul><ul><li>Life in water and on land as well 1 </li></ul>Etymology
  3. 3. Life Cycle <ul><li>egg in water  aquatic larvae  development of lungs and limbs  adult </li></ul><ul><li>Metamorphosis is observed 1 </li></ul>
  4. 4. Digestion <ul><li>take food through the mouth </li></ul><ul><li>frog has a long tongue with which it grabs insects for example </li></ul><ul><li>digestive system – stomach and intestines 10 </li></ul>
  5. 5. Reproduction <ul><li>Sexually </li></ul><ul><li>Eggs fertilized out of mother’s body (eggs are also called “spawn”) </li></ul><ul><li>Eggs layed in moist environments </li></ul><ul><li>Eggs dehydrate quickly because they don’t have shells 1 </li></ul>
  6. 6. Characteristics <ul><li>Symmetry: bilateral 2 </li></ul><ul><li>B orn in water but end up living on land. 1 </li></ul><ul><li>Skin: has glands; no feathers or hair; permeable and allows water and gas exchange (estivation = they “hide” during the summer so that their skin is moist; similar to hibernation when the body functions “slow down”) 8 </li></ul><ul><li>Eggs: no shell or membranes => it should be kept in a moist environment. 1 </li></ul><ul><li>Use gills to get oxygen from the water 1 </li></ul><ul><li>Amphibians are cold blooded (ectothermic) 3 </li></ul>
  7. 7. Representatives
  8. 8. Toad <ul><li>Latin Name : Bufo Bufo </li></ul><ul><li>Habitat : Fields, hedgerows, gardens and woodlands </li></ul><ul><li>Food : Worms, slugs and insects. </li></ul><ul><li>Range : throughout England, Scotland and </li></ul><ul><li>Wales, but not in Ireland. </li></ul><ul><li>Locomotion : Jumping; </li></ul><ul><li>hopping; swimming; burrowing; </li></ul><ul><li>Climbing 4 </li></ul>
  9. 9. Common Frogs <ul><li>Latin Name : Rana temporaria </li></ul><ul><li>Habitat : Shallow fresh water, including brooks, springs, and ponds </li></ul><ul><li>Food : i nsects, slugs and small worms </li></ul><ul><li>Range : Southeastern Canada; eastern U.S.; Central and Northern Europe, including Great Britain and Ireland </li></ul><ul><li>Locomotion: Jumping; hopping; </li></ul><ul><li>swimming; burrowing; climbing 5 </li></ul>
  10. 10. Smooth (Common) Newt <ul><li>Latin Name: Triturus vulgaris </li></ul><ul><li>Habitat : near ponds and streams; spend the winter under stones or logs (places with warmer temperature) </li></ul><ul><li>Food : Slugs, worms and insects </li></ul><ul><li>Range : Found throughout the UK ; Southeastern Canada and eastern U.S. </li></ul><ul><li>Locomotion : creeping ; </li></ul><ul><ul><li>swimming 6 </li></ul></ul>
  11. 11. Salamanders <ul><li>Latin name: Salamandra </li></ul><ul><li>Habitat : usually under stones </li></ul><ul><li>Food : insects, spiders, worms </li></ul><ul><li>Range : North America, parts of South America, Asia, Europe, North Africa, </li></ul><ul><li>Locomotion : creeping, walking 13 </li></ul>
  12. 12. Human Interactions/Uses of Amphibians; Common Ancestors <ul><li>Humans use some amphibians (frogs) for food </li></ul><ul><li>Amphibians share a common ancestor with mammals (Paleozoic era – about 300 MYA), that share common ancestors with humans 1 </li></ul>
  13. 13. Fun Facts <ul><li>Certain frogs can jump up to 20 times their own body length in a single leap. </li></ul><ul><li>Some frogs and salamanders have tongues 10 times the length of their body. </li></ul><ul><li>Most frogs can change their color to match their surroundings. </li></ul><ul><li>In most species of frogs only the male croaks because croaking attracts female frogs during mating season. 7 </li></ul><ul><li>The biggest frogs reach 1m in length, while the smallest are 12mm. 9 </li></ul>
  14. 14. Vocabulary <ul><li>Amphibians = organisms that live both on land and in water </li></ul><ul><li>Gills = an anatomical structure that helps the aquatic organisms to get oxygen from the water </li></ul><ul><li>Estivation = the process of hiding in the summer (resembles hibernating) in order for the amphibians to be moist </li></ul><ul><li>Metamorphosis = an extreme change in body form from one life stage to the next (tadpole to frog) </li></ul><ul><li>E ctothermic = cold blooded </li></ul><ul><li>Herpetology = the study of amphibians and reptiles </li></ul><ul><li>Spawn = amphibian eggs </li></ul><ul><li>Terrestrial = living on land </li></ul><ul><li>Hibernation = the process of “slow down” of the body functions </li></ul><ul><li>Caudata = amphibians that have tails 8 </li></ul>
