Our current knowledge on the carcharhinid sharks occurring in Turkey's seas comprises rudimentary data. Recently discovered photographic evidence suggests that Carcharhinus spp. have been present in the Sea of Marmara since the 1950s. This evidence also extends the known historical distributional range of Carcharhinus spp. into Marmaric waters, a northern extension of the Mediterranean basin. The results of previous and recent ichthyological inventories of the Sea of Marmara suggest that, currently, no species of the Carcharhinidae family occur in Marmaric waters. Further studies could provide an answer to the question: do any species of the Carcharhinidae family inhabit the Sea of Marmara?
