SCUBA Diving At Night: A Comparison To Human Behavior

As you may have noticed from my last post, I just got back from a SCUBA vacation.  And while on that trip Carissa and I completed several PADI Specialty Diver classes though our local shop (SeaVentures).  One of the ones that I did (and Carissa already had) was the Night Diver Specialty.  During the class you always get asked "so why do you want to complete the X specialty".  My answer was "to get more comfortable diving at night, and be able to appreciate the creatures that come out on the reefs after the Sun goes down".  I finished the specialty, got some good experience, and had fun doing it.  I wasn't prepared for what came next.
