How long does a fluke live for?

Flukes, which are parasitic flatworms belonging to the class Trematoda, typically have life spans that can vary widely depending on the species and environmental conditions. Some fluke species can live for several months to a few years within their hosts, while others may survive longer. For instance, the liver fluke (Fasciola hepatica) can live up to 10 years in its host. Overall, the longevity of flukes is closely tied to their life cycle and the survival of their hosts.
