Both fishing and a lot of marine science are generally all about dropping some bait in the water and seeing what happens. Swiped from Climate Shifts by way of DSN, here's a selection of possible outcomes when you drop a baited camera in the waters off Australia.
My personal favorites: the hammerhead repeatedly smacking against the camera (I can just imagine it thinking "curse you, evolution!") and the repeated, and ultimately successful, attempts by a massive tiger shark at separating bait from camera (including the near-demise of a sea snake hanging out in the wrong place at the wrong time).
Enjoy, and go Saints.
