Another interesting aspect in "snail" biology is their role as intermediate hosts for a wide 
variety of parasites of aquatic and terrestrial environments.  Parasitology textbooks will reveal 
the often amazing life cycles of those critters that often alter the behavior of their current host  
to promote the next developmental step, i.e. next host organism. Wouldn't surprise me to find 
out that in Spring and Fall some push for the step up in the next host (fish?).

Cheers

Ulli
