Dolphins are believed to have entered the Mediterranean and Black Sea through the Strait of Gibraltar, which connects the Mediterranean Sea to the Atlantic Ocean. It is thought that dolphins migrated from the Atlantic into the Mediterranean through this narrow passage. Once in the Mediterranean, dolphins have been able to thrive due to the favorable environmental conditions and abundant food sources. Similarly, dolphins are believed to have entered the Black Sea through the Bosporus Strait, which connects the Black Sea to the Sea of Marmara and ultimately the Mediterranean. **
