The Caspian Sea is the largest enclosed inland body of water in the world, located between Europe and Asia. It is bordered by five countries: Russia, Kazakhstan, Turkmenistan, Iran, and Azerbaijan. Despite its name, it is actually a lake, not a sea, and is known for its unique ecosystem, which includes various species of fish, such as the famous sturgeon. This vast body of water covers an area of about 371,000 square kilometers and has a rich history. The Caspian Sea has been a crucial trade route for centuries and is also significant for its oil and gas reserves. Its diverse landscapes and cultural heritage make it a fascinating destination for travelers and researchers alike.
