  9. Krill

  10. 30,000 Fish Species

  11. Mammals 4059 Birds 8750 Fish 23,700 Reptiles 5700 Amphibs 3750

  12. Why So Many Species ?

  13. What is the largest habitat on earth?

  14. The ship emits sound waves that reflect off the sea bottom and go back to the ship. Instruments on the ship measure how long the round trip took and compute the distance traveled. S. S. Ichthyology

  15. At night, the sound waves bounce off the layer of lantern fish and instruments on the ship are fooled into thinking that the ocean is shallow S. S. Ichthyology

  16. Lanternfish

  17. Light Organs

  18. Artesian wells flow without being pumped. Fish living 450 feet underground are sucked out of their homes by the well. 450’

  19. Trogloglanis pattersoni The fish are found in outflow from wells that penetrate the Edwards Formation between 402 m at the Artesia well and 582 m at the O.R. Mitchell. These are flowing artesian wells having considerable artesian pressure. Considering the amount of change in these species when compared to other species in their families, it seems logical to postulate that they found their way into the aquifer in prepleistocene times, perhaps as a means of escaping the colder temperatures on the surface.
