Fig. 2 in Threat of cercarial dermatitis in Hungary: A first report of Trichobilharzia franki from the mallard (Anas platyrhynchos) and European ear snail (Radix auricularia) using molecular methods

Fig. 2. The shape of bursa copulatrix of the adult R. auricularia is spherical and the stalk is long (A), while the bursa copulatrix of Radix balthica is oval and stalk is short (B). This anatomical structure seems the most reliable morphological difference to distinguish of the two most common Radix species in Hungary, but can only be studied on sexually mature and non-trematode infected specimens (Juh´asz, 2018) The length of the dissected organs is about 1 cm.
