Seas Bordering Southern Europe from Spain to Russia

There are five seas (not seven) bordering southern Europe from the Strait of Gibraltar to the Caspian Sea:

1. Mediterranean Sea (including sub-basins: Alboran, Balearic, Ligurian, Tyrrhenian, Ionian, Adriatic, Aegean, Levantine)
2. Sea of Marmara (Turkey — inland sea connecting Black & Aegean)
3. Black Sea (Bulgaria, Romania, Ukraine, Russia, Georgia, Turkey)
4. Sea of Azov (Russia/Ukraine — shallow northeastern arm of Black Sea)
5. Caspian Sea (Russia, Kazakhstan, Turkmenistan, Iran, Azerbaijan — world's largest lake, saline)

The Mediterranean's many named sub-seas (e.g., Aegean, Adriatic, Tyrrhenian) are sometimes counted separately, but hydrologically they form one connected sea.
