How could a snail cause death, you may ask? After all, aren’t they even slower than turtles? Well, these creatures infect water with a parasitic disease known as Bilharzia.
If you happen to swim in waters with freshwater snails, you could easily become infected with this disease and suffer from blood in the urine, diarrhea, abdominal pain, liver or kidney damage, bladder cancer and eventually, death. So, what is the moral of the story? Just avoid rivers or lakes where you think freshwater snails are living!
