Strongylus edentatus
parthenogony in trematodes occurs in what host
🐌 First intermediate host — the snail
🔬 What is parthenogony?
It’s a form of asexual reproduction where the miracidium develops into:
Sporocyst → Redia (in some species) → Cercaria
All this occurs inside the snail, without fertilization
