  1. Ichthyology: the study of fishes

  2. Vertebrate taxa

  3. Vertebrate taxa 4,100 6,500 species 24,500 species 8,600 species 850 species

  4. Vertebrate biases # pages in Larousse Encyclopedia of Animals 15 4% 148 37% 48 12% 61 15% 135 35%

  5. Number of species per order >9,000 species

  6. Define “fish”…..

  7. Fish extremes: Largest (SW): whale shark (12 m) Smallest: dwarf goby (Trimmatom nanus) – 8.0 mm carp Paedocypris progenetica – 7.9 mm

  8. Distribution of water vs. fishes

  9. Distribution of water vs. fishes

  10. Distribution of water vs. fishes 58% of all fishes 41% of all fishes

  11. Systems and sensory modalities of fishes • osmoregulation • buoyancy control • respiration (air and water) • mechanosensory – lateral line • light production • electroreception • electric generation • anatomically varied sound production
