A Trematode Parasite Infecting the Skin of Rana ridibunda Complex (Sensu Lato) from Dalaman (Mugla, Turkey)

We examined the structure of the black spots on the ventral surface of Rana ridibunda specimens, which were collected from the west Anatolia region of Turkey, and a multi-cellular parasite was discovered under these spots on the dermis within a cyst. The number of melanocytes had increased and the connective tissue of the dermis had surrounded the cyst. The parasite was a trematode in its metacercarial stage.
