There's an interesting paper about this snail feeding on native aquatic
snails in Hawaii.  The full reference is:
 
Kinzie,RA (1992): Predation by the introduced carnivorous snail Euglandina
rosea (Ferussac) on endemic aquatic lymnaeid snails in Hawaii. Biological
Conservation 60: 149-155.
 
In it Kinzie describes how Euglandina sits on the bank and sticks its head
underwater to track mucus trails from aquatic snails (lymnaeids).  Seems that
nothing is safe from this predator (except Achatina, of course, the very
think it was meant to control).
