Do marine snails forage for food when they are exposed to moisture from sea spray  and / or rain water?
     The purpose of my project is to observe the foraging behavior of marine snails when treated with different water solutions.  
I treated snails  with fresh and salt water solutions and observed for activity.  The detection of foraging was a bit problematic. I decided that movement when exposed to moisture consituted forgaging behavior. Snails with  foot and stalks out were assumed to be foraging.  I conducted my experiment at two locations:
