Monogenea
Monogenea
Monogenea (pronunciation: /ˌmɒnəˈdʒiːniə/) are a group of largely ectoparasitic members of the flatworm phylum Platyhelminthes, class Monogenea. They are commonly found in marine and freshwater environments, where they parasitize fish.
Etymology
The term "Monogenea" is derived from the Greek words "mono" meaning single and "genea" meaning generation. This refers to the fact that these parasites have a direct life cycle, with no intermediate hosts.
Description
Monogeneans are characterized by the presence of hooks, which they use to attach themselves to the gills, skin, or fins of their host. They are hermaphroditic, meaning each individual possesses both male and female reproductive organs.
Life Cycle
The life cycle of Monogenea is direct, meaning it does not require an intermediate host. Eggs are released into the water where they hatch into free-swimming larvae called Oncomiracidium. These larvae then seek out a suitable host.
