1. The miracidium penetrates the soft tissues of the snail, where it sporocyst. 2. Following this, a miracidium hatches, which swims to find a mollusc host. 3. Some eggs may be swallowed by a snail and hatch into larva ( miracidium ). 4. The eggs enter the water, and hatch into a miracidium larva within 2 weeks. 5. This system of asexual reproduction allows for an exponential multiplication of cercaria individuals from one miracidium . 6. The parasite s eggs hatch in the water and the miracidium invades the foot of the snails. 7. In the first intermediate host, the miracidium undergoes asexual reproduction for several weeks, which includes cercariae. 8. In the presence of open water, the eggs hatch and the miracidium stage of life is reached again. 9. The miracidium develops into a sporocyst, which in turn house the asexual reproduction of redia, the next stage. 10. Eggs in a wet environment hatch into miracidia in 9 14 days . The miracidium grows into the sporocyst stage.
