How can you identify the male fluke?

Male flukes can typically be identified by their smaller size compared to females and the presence of a unique structure called the copulatory bursa, which is used for mating. They also often exhibit more pronounced coloration or specific markings that differ from females. Additionally, male flukes usually have fewer reproductive organs than females, which are equipped with a more elaborate system for egg production. Observing these physical characteristics can help distinguish male flukes from their female counterparts.
