Only the Black Sea is connected to the Mediterranean by the intervening Sea of Marmara. However, within the Mediterranean itself there are subdivisions also known as seas. These are:
- the Strait of Gibraltar;
- the Alboran Sea, between Spain and Morocco;
- the Balearic Sea, between mainland Spain and its Balearic Islands;
- the Ligurian Sea between Corsica and Liguria (Italy);
- the Tyrrhenian Sea enclosed by Sardinia, Italian peninsula and Sicily;
- the Ionian Sea between Italy, Albania and Greece;
- the Adriatic Sea between Italy, Slovenia, Croatia, Bosnia and Herzegovina, Montenegro and Albania;
- the Aegean Sea between Greece and Turkey.
Finally, the Suez Canal connects the Mediterranean with the Red Sea.
