The Lancet Liver Fluke is part of the family of Platyhelminthes, and is considered one of the more complex parasites because, it goes through a life cycle. This organism is known in latin as Dicrocoelium dendriticum, and is often found with cattle when grazing. The parasite first finds a host in a snail after being hatch out of the feces of an animal, usually a cow or a goat. After growing and developing they are released in a slime ball only to be eaten by an ant which would infect cattle. The Lancet Liver Fluke lives, however, by diffusion. The organism, along with every other Platyhelminthes, gains the oxygen it needs from diffusion throughout its entire body.
