Sick fish - pelican or heron - infected snail - waterborne parasite.


I think you missed a step in there.

infected fish - heron - poop in water - infected snail - waterborne
parasite.

Yeah. Ewww. Another goes something like

infected fish - bird's throat - back in water while eating another
fish - infected snail - waterborne parasite - burrow into fish

Is that a weird lifecycle or what??? I'll stick to plain old sexual
reproduction, thanks. ;-)
