Abstract     
Here we describe a journey to the most southern corner of the European coast of the Black Sea during mid-September of 2013, visiting a creek near the town of Ahtopol as well as the rivers Veleka and Butamjata, Bulgaria. Before our visit the region suffered from a long dry summer and the creek near Ahtopol was almost dry so we were unable to provide information about the persistence of Mauremys c. rivulata in this most northern locality as previously reported by Rudloff (2007). However we could confirm the presence of Emys orbicularis in a small remaining ditch of heavily polluted water below a bridge. During a boat trip on the Veleka we report about the presence of and co-existence of Emys orbicularis and M. c. rivulata of various sizes including also subadult age classes as well as adult Trachemys scripta elegans. Along the Butamjata river we were able to locate one juvenile (CL 50–60 mm) M. c. rivulata. Therefore we were able to confirm the presence of three species of freshwater turtles as reported for Bulgaria (Stonjanov et al. 2011) for the Veleka including a short discussion about the situation of invasive species.
