The Adriatic Sea is a body of water that separates the Italian Peninsula from the Balkan Peninsula. It's the northernmost part of the Mediterranean Sea, stretching about 800 kilometers (500 miles) from the northwest to the southeast.

The Adriatic is known for its beautiful blue waters, rich marine life, and important coastal regions. It connects to the rest of the Mediterranean Sea through the Strait of Otranto. The sea is relatively shallow compared to other parts of the Mediterranean, with an average depth of about 252 meters (827 feet).
