Fish drashkov kardjaliev valcheva 10 6

  1. 1. Toma Drashkov Robert Kardjaliev Neda Valcheva 10/6 Fish
  2. 2. Circulation <ul><li>Oxygen poor blood from sinus venosus </li></ul><ul><li>Atrium </li></ul><ul><li>Ventricle </li></ul><ul><li>Oxygen poor from conus arteriosus to get oxidized by gills and then goes to the rest of the body </li></ul>
  3. 3. Digestion <ul><li>Food is broken first in esophagus </li></ul><ul><li>In stomach the pyloric caeca secretes enzymes, absorbs nutrients </li></ul><ul><li>The cycle ends in the intestines </li></ul>
  4. 5. Movement <ul><li>Muscles, Fins, Skeleton </li></ul><ul><li>S movement </li></ul><ul><li>Very aerodynamic form </li></ul><ul><li>Liquid secreted to minimize drag </li></ul><ul><li>http://www.youtube.com/watch?v=GUtajoVi8qw </li></ul>
  5. 6. Interesting <ul><li>Fish have a vision as good as ours </li></ul><ul><li>Have ears, cannot hear very well </li></ul><ul><li>Sense gentle currents, vibrations, movement </li></ul><ul><li>Some (shark, catfish) detect low electric Currents </li></ul><ul><li>Some (electric eel) produce electric current </li></ul>
  6. 7. Main Groups <ul><li>Not a single clade, but 3 main groups </li></ul><ul><li>Agnatha - j awless primitive fish </li></ul><ul><li>Chondrichthyes – jawed fish; cartilaginous skeletons </li></ul><ul><li>Osteichthyes - bony fish; fish with bony skeletons </li></ul>
  7. 8. Symmetry <ul><li>Some fish have bilateral symmetry </li></ul><ul><li>However, not all – they come in all shapes and sizes as can be seen in (a) and (b) </li></ul>http://image.tutorvista.com/content/animal-kingdom/cray-fish-and-hydra-symmetry.jpeg http://image.tutorvista.com/content/animal-kingdom/cray-fish-and-hydra-symmetry.jpeg
  8. 9. General Things About Fishes <ul><li>Live underwater in both fresh and salt water </li></ul><ul><li>Free swimming or laying on the bottom of the sea </li></ul><ul><li>Not a single clade; 3 main groups </li></ul><ul><li>Their way of breathing is different from that of other species due to their living underwater </li></ul><ul><li>They come in a plethora of shapes and sizes </li></ul><ul><li>Have different ways of reproducing </li></ul>
  9. 10. Agnatha <ul><li>Petromyzon marinus or sea lampreys live in the Great Lakes in North America </li></ul><ul><li>Live for 10 years and feed off from the blood and tissue of teleost fishes </li></ul><ul><li>Eggs-> blind & toothless larvae-> live burried in mud, filter-feeding->metamorphosize into adults and turn into their parasitic form -> spawn 60-70 thousand eggs-> die </li></ul>
  10. 11. Chondrichyes <ul><li>The Great White Shark, Carcharodon carcharias , can be found in coastal surface area in all oceans </li></ul><ul><li>Live 30-100 years long </li></ul><ul><li>Largest predatory fish – up to 6 meters long </li></ul><ul><li>No natural enemies other than humans </li></ul><ul><li>Not much known about their life cycle except that they give birth to 2-14 baby sharks and migrate often </li></ul>
  11. 12. Osteichthyes <ul><li>Pacific Salmon, Oncorhynchus, from the Salminodae family live in the Great Lakes and the Pacific Ocean </li></ul><ul><li>Food diet depends on where they live; generally, zooplankton and smaller fishes </li></ul><ul><li>Born in fresh water but migrate and spend most of their life in salt water </li></ul><ul><li>Have six life cycle stages eggs-> alevin-> fry-> smolt-> adult-> spanwer </li></ul><ul><li>Used as food </li></ul>
