Dicrocoelium dendriticum - Wikipedia
Dicrocoelium dendriticum spends its adult life inside the liver of its host. After mating, the eggs are excreted in the feces.
The first intermediate host, the terrestrial snail (Cochlicopa lubrica in the United States), consumes the feces, and becomes infected by the larval parasites. The larvae (or miracidium) drill through the wall of the gut and settle in its digestive …Wikipedia · Text under CC-BY-SA license- Estimated Reading Time: 8 mins
