Presentation Transcript

  1. Fishes

  2. Fishes - Biology • Body Shapes • Strongly related to lifestyle

  3. Fishes - Biology • Body Shapes • Fusiform Video

  4. Fishes - Biology • Body Shapes • Laterally Compressed Video

  5. Fishes - Biology • Body Shapes • Flattened

  6. Fishes - Biology • Body Shapes • Eel-like Video

  7. Fishes - Biology • Body Shapes • Unusual, Irregular Video

  8. Fishes - Biology • Coloration • Color comes from pigments in chromatophores • Structural colors come from iridophores • Warning Coloration • Cryptic Coloring • Disruptive Coloring • Countershading

  9. Fishes - Biology • Coloration Warning Disruptive Cryptic Countershading

  10. Fishes - Biology • Locomotion • Most fish use rhythmic side to side motion of body produced by myomers • Sharks and Rays

  11. Fishes - Biology • Locomotion • Bony Fishes • Eel-like • Cadual • Dorsal/anal • Pectoral • Other

  12. Fishes - Biology • Feeding • Sharks and Cartilaginous Fish • Carnivores that bite pieces off larger prey • Ingest smaller prey whole • Filter plankton using gill rakers video Pictures

  13. Fishes - Biology • Feeding • Bony Fish • Capture large prey whole • Pickers – ingest small prey whole • Grazers • Filter Plankton

  14. Fishes - Biology • Feeding • Bony Fish

  15. Fishes - Biology • Circulatory System

  16. Fishes - Biology • Respiratory System • Irrigation of gills

  17. Fishes - Biology • Respiratory System • Gill Structures

  18. Fishes - Biology • Respiratory System • Gill Structures

  19. Fishes - Biology • Regulation of Internal Environment • Chondricthyes

  20. Fishes - Biology • Regulation of Internal Environment • Bony Fish
