What is Gymnophallus somateriae?

Gymnophallus somateriae is a species of trematode, or flatworm, belonging to the family Gymnophallidae. It is primarily a parasite found in the intestines of fish-eating birds, with a complex life cycle that involves various host species, including snails and fish. This trematode is notable for its morphological adaptations that facilitate its parasitic lifestyle. Understanding its Biology contributes to the broader study of host-parasite interactions in aquatic ecosystems.
