Abstract

Abstract A stranding of a Risso’s dolphin (Grampus griseus) was reported for the first time in the Marmara Sea, Turkey. A piece of rope tied around its tail fluke can be the evidence of bycatch. The occurrence of the Risso’s dolphin, dead or alive, was never reported before in the Marmara Sea.
