Index of Subjects 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
