| 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.
