There are many reasons why freshwater snails are so dangerous. One reason is because they can carry and transmit a number of diseases to humans including schistosomiasis which is a parasitic disease that can cause severe health problems including liver damage intestinal damage and even death.
Another reason why freshwater snails are so dangerous is because they can act as intermediate hosts for a number of parasites including the larvae of the fatal disease-causing Naegleria fowleri amoeba. This amoeba is commonly found in warm freshwater lakes and rivers and can enter the human body through the nose causing severe brain damage and death.
Freshwater snails can also pose a danger to animals. For example they can transmit the heartworm Dirofilaria immitis to dogs which can cause serious health problems including heart failure and death.
In conclusion freshwater snails are dangerous because they can carry and transmit a number of diseases to humans and animals and can also act as intermediate hosts for a number of parasites.
