Polyopisthocotylea [Polyopisthocotylea]
Description
Polyopisthocotylea is an order of monogenean parasites recognized for their multiple opisthaptors, which are attachment structures equipped with clamps. This distinctive feature allows them to firmly attach to the gills of both marine and freshwater fishes. Polyopisthocotylea species are varied in their morphology and life strategies, but they commonly possess complex life cycles with direct transmission. They are significant in fish health management due to their role in various fish diseases and their ability to spread rapidly within populations.
