  1. Fishes - Biology • Respiratory System • Gill Structures

  2. Fishes - Biology • Respiratory System • Gill Structures

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

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

  5. Fishes - Biology • Sensory Systems • Smell/Taste • Sensory cells in olfactory sacs • Lateral lines

  6. Fishes - Biology • Sensory Systems • Inner Ear • Calcareous otoliths – rest on sensory hairs

  7. Fishes - Biology • Sensory Systems • Electro Magnetic Fields

  8. Fishes - Biology • Behavior • Schooling Swimming Feeding Predator Avoidance

  9. Fishes - Biology • Behavior • Migration Anadromous Transoceanic

  10. Fishes - Biology • Behavior • Migration • Anadromous • Spend most of life in ocean and spawn in freshwater • Salmon – use smell and magnetic field to find home river • Salmon – habitat destruction impacts reproduction ability

  11. Fishes - Biology • Behavior • Migration • Catadromous • Spend most of life in freshwater and spawn in saltwater
