Liver flukes have a complex life cycle involving snails. Adult liver flukes lay eggs in the bile ducts of the liver, the eggs are passed out through faeces. Under warm and humid environmental conditions, they hatch into a stage that requires snails for further multiplication.
As the name suggests, this worm attacks the liver. A liver fluke’s life cycle is dependent on water and snails. Liver flukes colonize and destroy the liver tissue of ruminants.
